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

Abstract

Abstract⎯ 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 D PI λ 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 D PI λ μ design for filter.The results shown that Implement the Fractional-order D PI λ μ provides the minimum of steady-state error and improved delay time at the output of controller Keywords−fractional-order D PI λ μ ;transconductance amplifier; fractional-order rational approximation; fractional-order D PI λ μ design
