Introduction to Simulink   Simulink Introduction and Key Features In this demo, we introduce the key capabilities of Simulink with examples.   Simulink Demo: Getting Started Video   This video demo gets you started with Simulink. It takes you through many key concepts in building and simulating a model. We will build up a model from scratch while taking you through a number of features of Simulink.   General Application Examples   Modeling a Bouncing Ball   In this demo, we model a ball bouncing on ground using zero crossing detection feature in Simulink.   Approximating Nonlinear Relationships: Type S Thermocouple This demonstration will focus on models for each of these components in a dynamic temperature measurement system for a Type S thermocouple device and probe assembly, a signal conditioning method, an analog to digital converter (ADC), and a software specification for converting the ADC output into a temperature value.   Digital Waveform Generation: Approximating a Sine Wave This demonstration goes through some of the main steps needed to design and evaluate a sine wave data table for use in digital waveform synthesis applications in embedded systems and arbitrary waveform generation instruments.   Simulating Systems with Variable Transport Delay Phenomena This demo shows two examples of how you can use Simulink to model variable transport delay phenomena.   Single Hydraulic Cylinder Simulation   This demo uses Simulink to model a hydraulic cylinder. You can apply these concepts to applications where you need to model hydraulic behavior.   Thermal Model of a House   This demo illustrates how you can use Simulink to create the thermal model of a house. This system models the outdoor environment, the thermal characteristics of the house, and the house heating system.   Spiral Galaxy Formation Simulation Using Embedded MATLAB Functions   This demo provides insight into how our own galaxy evolved. It allows the user to maximally simplify the model and run a fast simulation. The user can easily modify the demo by adding more galaxies.   Modeling a Foucault Pendulum   This demo simulates a 67 meter long Foucault pendulum at the geographic latitude of Paris.   Exploring Variable-Step Solvers Using a Stiff Model   This demo explores the behavior of variable-step solvers in a Foucault pendulum model. Simulink solvers ode45, ode15s, ode23, and ode23t are used as test cases.   Automotive Application Examples   Automotive Powertrain Control System This video demonstration, presented in several short segments, illustrates Model-Based Design for an automotive powertrain controller.   Automotive Power Window System In this case study we model an automotive passenger power window system using Model-Based Design with Simulink, Stateflow®, SimMechanics™, and SimPowerSystems™ . We will design the controller from a set of requirements, build a plant model to test the controller, and finally verify that the controller meets the requirements.   Modeling Engine Timing Using Triggered Subsystems   This demo presents a model of a four-cylinder spark ignition engine and demonstrates Simulink capabilities to model an internal combustion engine from the throttle to the crankshaft output.   Engine Timing Model with Closed Loop Control In this demo, the objective of the controller is to regulate engine speed with a fast throttle actuator, such that changes in load torque have minimal effect.   Clutch Lock-up Simulation This example demonstrates the use of Simulink to model and simulate a rotating clutch system.   Clutch Simulation Using If Block This demonstration shows how to use If/Else subsystems to build a clutch model. An 'If' subsystem models the clutch dynamics in the locked position while an 'Else' subsystem models the unlocked position.   Modeling an Anti-Lock Brake System This demo describes a simple model for an Anti-Lock Braking System (ABS). It simulates the dynamic behavior of a vehicle under hard braking conditions.   Modeling a Fault-Tolerant Fuel Control System The following example illustrates how to combine Stateflow with Simulink to efficiently model hybrid systems.   Modeling an Automatic Transmission Controller In this demo, Simulink is used to model an automotive drivetrain. Stateflow enhances the Simulink model with its representation of the transmission control logic.   Simulating Automatic Climate Control Systems In this demo we use Simulink and Stateflow to simulate the working of an automatic climate control system in a car.   Vehicle Electrical and Climate Control Systems   This demo model interfaces the vehicle climate control system with a model of the electrical system to examine the loading effects of the climate control system on the entire electrical system of the car.   Automotive Suspension   This demo describes a simplified half-car model that includes an independent front and rear vertical suspension. It provides a description of the model to show how simulation can be used to investigate ride characteristics.   Communications and Electronics Application Examples   HDL Generation of Digital Filters This demonstration illustrates Model-Based Design for a fixed-point filter for implementation on FPGA or ASIC hardware. We will automatically generate synthesizable HDL and verify implementation through cosimulation with ModelSim.   Video Streaming Over Networks   In this demonstration, we model a communication system that sends frames of video data over a channel. By dropping frames that wait too long to reach the end user, the model also illustrates how to use timeouts to implement point-to-point timing constraints.   Modeling a Simple Communication Link   In this demonstration, we show how you can model a simple communication link using Simulink, Signal Processing Blockset™ and Communications Blockset™.   Aerospace Application Examples   Spacecraft Automatic Landing System   In this video demo, we model an automatic landing system for the HL-20, a spacecraft based on a specification from NASA.   Apollo Lunar Module Digital Autopilot In this demo, one of the engineers who worked on the Apollo Lunar Module digital autopilot design team describes how he would have done it using Simulink® if it had been available in 1961.   F-14 Digital Flight Control This demo illustrates how to use the Control System Toolbox™ and Simulink® Control Design™ to interact with Simulink to design a digital pitch control for the U.S. Navy's F-14 Tomcat aircraft.   Radar Tracking Using Embedded MATLAB This demo shows how to use an extended Kalman filter with the Embedded MATLAB™ Function block in Simulink to estimate an aircraft's position from radar measurements. The filter implementation is found in the Embedded MATLAB Function block, the contents of which are stored in the Simulink model itself.   Designing an Aircraft Elevator Control System   In this case study, we use Model-Based Design with Simulink, Stateflow, and Simulink® Verification and Validation™ to design a fault detection, isolation, and recovery (FDIR) application for a pair of aircraft elevators with redundant actuators. We then use requirements-based testing in order to verify that these requirements have been met.   Air Traffic Control Radar Design   In this demo, the model is a conceptual air traffic control (ATC) radar simulation based on the radar range equation.   Industrial Automation and Machinery Application Examples   Modeling of a DC Motor   In this demonstration, we show how you can use Simscape™ with Simulink to build a model of a DC motor.   Modeling of a Piston   In this demonstration, we show how you can model a piston in a reusable way within the Simulink environment using SimMechanics™.   Modeling of Conveyor Mechanism   In this demonstration, we show how you can use SimMechanics with Simulink to expand the model development environment into the physical modeling world, allowing the mechanical plant and the controller to be designed at the same time.   Robot-Arm Control System using xPC Target™   This demo shows how you can setup, interact, and control a robot arm in real-time with xPC Target. Highlights include showing how you can tune parameters, log data, and interface with a robot arm from Simulink and the xPC Target Explorer.
