Implement the fractional-order, half integrator and differentiator on the OTA base PI^λD^μ controller circuit

摘要

Proportional integral-derivative (PID) control is one of method to use in the control system or feedback control. In this paper presents the optimum output of controller by used the fractional-order PI^λD^μ is verified on the operational transconductance amplifier (OTA) analogue circuit. The method of approximation function and circuit design are presneted and shown simple of fraction-order PI^λ D^μ design for filter. The results shown that Implement the Fractional-order PI^λD^μ provides the minimum of steady-state error and improved delay time at the output of controller
