Position Servo Control Algorithm Based on Optimal Solution Analysis of Motion Control

Based on the d-q axis voltage equations and motion equations of a permanent magnet synchronous motor (PMSM), this paper analyzes the factors influencing the motor’s output electromagnetic torque and rotor acceleration. A theoretical optimal model for the positional servo control of a specific mechanism is established. Furthermore, a positional servo control algorithm tailored for this mechanism is proposed. Experimental validation is conducted through the construction of a physical experimental system, with a focus on analyzing the response speed, servo accuracy, and robustness of the motor’s positional servo process. Experimental results demonstrate that under the control of this algorithm, the motor exhibits rapid response speed, and its servo accuracy and robustness meet the requirements, making it of practical engineering significance.
