摘要：AbstractThe purpose of this paper is to introduce an advanced virtual tool for fractional PID (FPID) controller design. It implements generic Nyquist plot shaping and/or sensitivity functions shaping capabilities. In this context, one can define e.g. gain and phase margins, sensitivity functions limits or loop bandwidth. The procedure relies on generalized robustness regions method for fractional PID controllers. The technique is best applicable namely for any non-oscillatory or slightly oscillatory linear system even with dead time, both integer and fractional order. The robustness regions can be computed and painted for more system models hence the robust controller design can be done. Here the method is validated on three illustrative examples. The author believes, that the virtual lab will be worthwhile for both researchers and industrial practitioners and will help to boost the employment of fractional order PID controllers.
