Controller Functions

Modules

 PID Motor Control
 

A Proportional Integral Derivative (PID) controller is a generic feedback control loop mechanism widely used in industrial control systems.


 Vector Clarke Transform
 

Forward Clarke transform converts the instantaneous stator phases into a two-coordinate time invariant vector.


 Vector Inverse Clarke Transform
 

Inverse Clarke transform converts the two-coordinate time invariant vector into instantaneous stator phases.


 Vector Park Transform
 

Forward Park transform converts the input two-coordinate vector to flux and torque components.


 Vector Inverse Park transform
 

Inverse Park transform converts the input flux and torque components to two-coordinate vector.
