ABSTRACT:
Apart from the object, a controller constitutes one of the fundamental elements of control systems. However, such controllers, even in SISO (Single Input, Single Output) systems where a single output is controlled by a single input, may not be the most appropriate choice. Moreover, a PID controller may not be easily tuned to any setup. The paper outlines three elementary methods for tuning the controller. Results of the process conducted by means of Ziegler-Nichols, Cohen-Coon, and Lambda methods were compared in Matlab.
