Hardware Implementation and Performance Study of Analog PIλDμ Controllers on DC Motor

Abstract

In this paper, the performance of an analog PI λ D μ controller is done for speed regulation of a DC motor. The circuits for the fractional integrator and differentiator of PI λ D μ controller are designed by optimal pole-zero interlacing algorithm. The performance of the controller is compared with another PI λ D μ controller—in which the fractional integrator circuit employs a solid-state fractional capacitor. It can be verified from the results that using PI λ D μ controllers, the speed response of the DC motor has improved with reduction in settling time ( T s ), steady state error (SS error) and % overshoot (% M p ).

Identification of Fractional Models of an Induction Motor with Errors in Variables

“…Fractional-order differentiation constitutes a valuable instrument for modeling real-world processes. Fractional calculations are widely used for the synthesis of fractional controllers for various electric motors including, among others, induction motors [16][17][18][19], direct current (DC) motors [20], and permanent magnet synchronous motors (PMSMs) [21]. The aforementioned research on the topic always assumed that induction motor models were of an integer order.…”

“…Hence, improving the quality of its control is significant to avoid machine damage. Although various control schemes are used in DC motor control [3][4][5], the PID controllers are widely used in speed control applications due to their simplicity, flexibility in tuning, and implementation [6][7][8]. However, these controllers cannot handle disturbance and parameter variations.…”
