【摘要】：电机过热时会造成绕组绝缘降低,严重时会烧坏电机。传统的双通道PID控制算法降低了对电机温度的控制精度,导致电机过热。提出一种基于自抗扰控制算法(ADRC)的电机温度控制方法,以双通道PID控制方法为基础进行了改进,对内外扰动进行综合处理,对扩张状态观测器进行估计,并在反馈中引入非线性特性。仿真实验中,在电压电流均改变30%的情况下,改进算法仍能实现温度的精准稳定控制。比传统算法稳定性强,准确率提高36.5%,适合推广应用。
[Abstract]:Motor overheating will cause the winding insulation is reduced, which will burn out the motor. The traditional dual channel PID control algorithm reduces the control precision of the temperature of the motor, the motor is overheated. Put forward a kind of algorithm based on Active Disturbance Rejection Control (ADRC) method to control the temperature of the motor, with dual channel PID control method based on improved, to carry out comprehensive treatment of internal and external disturbances, estimate the extended state observer, and the introduction of the nonlinear characteristics in the feedback. In the simulation, voltage and current were changed in 30% of the cases, the improved algorithm can achieve accurate and stable temperature control. The stability and accuracy of 36.5%, which is suitable for popularization and application.
