The post Closed-Loop Step Response for Tuning PID Fractional Order Filters [technical] first appeared on the ISA Interchange blog site.
Abstract: Analytical methods are usually applied for tuning fractional controllers. The present paper proposes an empirical method for tuning a new type of fractional controller known as PID-Fractional-Order-Filter (FOF-PID). Indeed, the setpoint overshoot method, initially introduced by Shamsuzzoha and Skogestad, has been adapted for tuning FOF-PID controller. Based on simulations for a range of […]
