Simulation Of Startup Speed of DC Motor Using PI And PID Control

Abstract

Proportional-Integral (PI) control and Proportional-Integral-Derivative (PID) control have found widespread application across various disciplines. This article focuses on the impact of PI and PID control on the startup speed of the Direct-Current (DC) motor. By setting up a simulation circuit and simulation module, the gain parameters of the control module are adjusted to obtain different output results. The simulation circuit will involve the DC motor, the control module, and the desired speed input. By adjusting the gain parameters of the control module, the behavior of the motor's startup speed can be simulated and observed. For PI control, increasing both the proportional gain and the integral gain proportionally can lead to shorter settling time and smaller overshoot in the output response. For PID control, increasing the derivative gain can significantly reduce the settling time without causing a significant change in the overshoot. When comparing PI and PID controllers, the addition of the derivative term can improve the output performance. By simulating different control modules and adjusting the gains, it is possible to qualitatively identify controllers with better control performance and more suitable gain parameters. This provides insights for the future design and application of DC motor control modules.
