Proportional-Integral-Derivative controllers are the most widely used ones in industry, actually, more than ninety percent of all the implemented controllers are PID controllers, this obviously shows the PID controller importance.

In spite of its relative simplicity, the design of the PID controller is not limited to tuning of its three coefficients. Various factors, including controller structure, process degree, ratio of dead-time to dominant time constant, derivative filter design and its tuning, integrator windup and system non-linearity, etc, can affect the controller performance.

Among these factors, two important ones are: Derivative filter design, and integrator windup effect, which we will discuss in detail in this project.

First of all, basics of PID control, its different structures, and some modifications of the basic PID control law, along with some guidelines of choice of controller type are discussed.

In the Derivative Filter Design chapter, we emphasis on four-parameter tuning of PID controller and represent several simulation to show the effectiveness of the method. Besides, the performance of the derivative filter on different structures of the controller is discussed.
