Controller is nothing but to get a nearest set value by calculating eror value.
P stands for present error
I stands for past error
D stands for future error
The main use for the pid controller is to be a generic control loop feed back mechanism (the controller) and the pid controller is widely used in all areas of the world.
The units of a PID controller are typically in terms of time, such as seconds or minutes, for the integral and derivative components, and in terms of a ratio for the proportional component.
A proportional-integral-derivative controller(PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems. A PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the error minimal.

Yes, it is possible to convert a PID controller into state space form. A PID controller can be represented in a state-space framework by defining the proportional, integral, and derivative actions as state variables. This allows for the incorporation of the PID control law into a state-space model, facilitating analysis and design in a unified format suitable for modern control strategies.
To control linear actuator by PID controller, use the data from the feedback device. Use the potentiometer to adjust the output until it reaches the target value.
A PID Controller works by correcting the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly - and rapidly - to keep the error minimal.A proportional-integral-derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems.
