摘要
基于永磁同步电机的二惯性特征对电机速度环PID控制参数的整定进行了研究,得到了固有频率为100rad/s的系统在达到设定评价指标时的PID参数整定规律。为了简化过程,将多个变量归结为3个变量,分别是质量比x1、频率比x2和阻尼比x3,并给出了基于仿真数据点的拟合公式。最后通过MATLAB验证了拟合公式在缩短参数调节时间方面的有效性。
Based on the two-inertia characteristic of permanent magnet synchronous motor, the tuning of PID control parameters of motor speed loop was studied. The tuning rule of PID control parameters that made the system satisfy the evaluation criteria was studied when the natural frequency was 100 rad/s. To simplify the process, multiple variables were handled to three variables, frequency ratio x2, mass ratio x1, damping ratio x3. The fitting formula based on simulation data points was also given. Finally, the validity of the formula in shortening the time of parameter adjustment was verified by MATLAB.
