Abstract:

Selection of a suitable controller type, determination of its coefficients and adjustment if necessary is an important issue in the design of control systems. Quickly checking whether the closed-loop system with a designed controller meets some desired time/frequency response criteria will save time for the student/designer. In this paper, an interactive control system simulator is designed to perform the simulations for closed-loop systems obtained with user-defined systems and different types of controllers whose parameters can be changed. The simulator allows the user to see the time/frequency response of the closed-loop system for different systems defined as single or comparatively and check whether some desired time/frequency domain criteria are satisfied, quickly. In addition, the simulator allows the possibility to see the disturbance input response and the effect of the measurement noise altogether with the reference input response, comparatively. Thus, analysis and comparison of different controllers and also teaching of control systems will be performed easily, quickly and effectively by using the simulator.
