SimElectronics

Overview

SimElectronics^® provides component libraries for modeling and simulating electronic and mechatronic systems. It includes models of semiconductor, motor, drive, sensor, and actuator components. You can use these components to perform system-level design of electromechanical actuation systems and to evaluate analog circuit architectures using behavioral models.

Modeling a DC Motor with Driver 7:10
Model a DC motor along with a pulse-width modulation (PWM) driver. Averaged and detailed driver models are used to balance the tradeoff between model fidelity and simulation speed.

Models created from SimElectronics components support control and algorithm design in electronic and mechatronic systems, such as vehicle body electronics, aircraft servomechanisms, and audio power amplifiers. For circuit modeling, the semiconductor models include nonlinear and dynamic temperature effects, enabling you to select components in amplifiers, analog-to-digital converters, phase-locked loops, and other circuits.
