PID controller tuning appears easy, but finding the set of proportional, integral, and derivative gains that ensures the best performance of your control system is a complex task.

MATLAB^® and Simulink^® make PID tuning easy, by letting you:

• 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
• 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
