AbstractMotor speed control is a critical aspect of many industrial and commercial applications. This paper investigates the performance of two widely used control techniques, Linear Quadratic Regulator LQR and Proportional-Integral-Derivative PID, for motor speed control. We perform a simulation study using MATLAB to compare the performance of these two controllers in terms of their ability to track the reference speed profile. The simulation results show that LQR and PID controllers can achieve accurate speed tracking, but their performance characteristics differ significantly. LQR is better in the steady state and overshoot but slower than PID. Our study provides insights into the trade-offs between these two controllers and can guide the selection of an appropriate control technique for a given motor speed control application.
