The PID controller is by far the most common algorithm. Most feedback loops are controlled by this algorithm or minor variations of it. Ttraditionally the PI controller has been widely used, while some other types of PID controller have been applied in some applications. In this article, the modified PI controller which has the feedforward term is introduced. In order to achieve desired performance criteria such as quick response, reference tracking, steady state error, system bandwidth and disturbance rejection capability, an optimization procedure for classical PI and modified PI controller is introduced with experimental results. The characteristic of current control loop of vector controlled induction machine with classical PI and modified PI controllers is also discussed along with experimental results.
