PID Control with MATLAB and Simulink

Design and implement PID controllers

PID tuning and implementation involve several tasks that include:

• Selecting an appropriate PID algorithm (P, PI, or PID)
• Tuning controller gains
• Simulating the controller against a plant model
• Implementing the controller on a target processor

MATLAB and add-on products bring efficiency to these design tasks by enabling you to:

• Configure your Simulink PID Controller block for PID algorithm (P,PI, or PID), controller form (parallel or standard), anti-windup protection (on or off), and controller output saturation (on or off)
• Automatically tune controller gains and fine-tune your design interactively
• Tune multiple controllers in batch mode
• Run closed-loop system simulation by connecting your PID Controller block to the plant model
• Automatically generate C code for targeting a microcontroller
• Automatically generate IEC 61131 structured text for targeting a PLC or PAC
• Automatically scale controller gains to implement your controller on a processor with fixed-point arithmetic
