What is discrete PID controller?

The Discrete PID Controller block implements a PID controller (PID, PI, PD, P only, or I only). The block is identical to the PID Controller block with the Time domain parameter set to Discrete-time .

How do you discretize a PID?

A straightforward way to discretize this controller is to convert the integral and derivative terms to their discrete-time counterpart. There are commonly 3 variations to do so, by means of forward Euler, backward Euler, and trapezoidal methods.

What is the basic difference between a discrete PID controller and continuous PID controller?

Continuous-time controller is designed in the s-domain, whereas a discrete-time controller is designed in the z-domain. Therefore you cannot use the same numeric values to obtain the same response. Continuous is implemented with analogue electronics. Discrete means digital.

What is dynamic PID controller?

A PID (Proportional-Integral-Derivative) controller is a control loop feedback mechanism widely used in industrial control systems and other applications requiring continuously modulated control.
