PID Control with MATLAB and Simulink

Design and implement PID controllers

PID control is ubiquitous. While simple in theory, design and implementation of PID controllers can be difficult and time consuming in practice.

PID control involves 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
