Özet

In process control, inherited large time delays both in feedback line and actuator dynamics compromise the stability and the performance of the system especially with the fast acting controllers. The new method utilizes Kronecker multiplication and palindromic polynomials to reduce the order of the characteristic equation to ease the digital controller design. Furthermore, the method facilitates rightmost root placement to implement controllers which increases the performance of the control action. In this study, we present the new controller design method and its application on an industrial experimental case.
