Design better PID control with confidence

PID controllers are very popular in industry due to their simplicity of implementation. They are often tuned with methods like Ziegler-Nichols. They don't always work as well in practice as they should, however. In many cases, you will understand the system better and achieve superior results with simulation.

PID loop to control a process. PID controllers consist of Proportional, Integral or Derivative elements. They can be implemented as PI controllers, PD controllers as well. Proportional Control sets the gain of the loop. The PID process can be implemented as an analog control system or digital control system in a processor.

Make realistic system models with SimApp

The first step to success is to make a good model of the dynamic system. Dynamic systems can change with environmental conditions or from system to system. In addition, they may have non-linear effects or external inputs that affect their performance or stability. You can make realistic models with SimApp to evaluate these situations.

Design stable, high-performance control systems

Once the dynamic system is understood, the PID loop can be designed to perform to specification with non-ideal system and parameter variations included. SimApp has many types of PID controlers built-in. The final result may be a traditional PID system, or a control system that is custom-tuned for the actual situation.   Please refer to our white paper:  PID Control Design - Beyond the Recipe
