Several decades have seen the widely application of PID controllers and the design and tuning methods have been of considerable development. This version of Internet Explorer is no longer supported by Microsoft , and some features of our store may no longer be supported by this version of IE. The methods can be used experimentally on physical systems, but also on simulated systems. Angle/Horizon modes have their own values that interfere with tuning. With the controller embedded in the real system, increase or decrease K in order to change the transient response of the compensated system with the view to meeting transient performance specifications. Many papers have proposed different tuning algorithms to reduce this problem. LAB-1: PID control 1 Introduction The main objective of this laboratory is to get a basic understanding for how feedback control can be used to modify the behavior of a dynamic system.
