Hi
PID controller is the most popular controller in the industries. Performance (speed and accuracy) of the controller is determined by the controller parameters. There are many tuning methods available, but most of them are applicable to certain class of the system. Although some tuning work well in simulation but not in Real time application because of the measurement noise and non-linear behaviour occur in Real-time. In real time tuning the derivative action is very difficult. so very often modified version is used for derivative. Kds/(1+Ts) is given in the K. J. Astrom etal (The PID control ) text book. But this particular filter doesn’t improve my real time measurement noise signal.
Can any one tell me another way to design a derivative filter?
Thank you so much for your help in adavance.
