A fast and efficient digital simulation technique for control systems

Abstract

The new simulation technique uses a digital compensator in the forward path immediately after the error detector in a typical closed loop system. This compensator contains two parameters which can be tuned to obtain very accurate results. This technique was used on a second order closed loop system with a non linear element in the forward path. The results show great improvement over the substitution methods (Halijak and Tustin). When another compensator was introduced in the feedback path, the results are comparable to the highly accurate T-integrator method.
