摘要
提出一种带负载力矩干扰补偿的直流调速系统.利用系统中可测量到的电枢电流和转速信号,通过线性网络获得系统中不可直接测量的负载力矩的等效信号,并使此信号参与系统的控制作用,从而克服负载力矩对电机转速的影响.仿真实验结果表明系统不仅具有良好的静、动态性能,而且具有较强的抗负载力矩干扰能力.
A D.C. motor speed control system with a load torque compensation is presented in this paper. The equivalent load torque will be obtained by using measurable armature current and motor speed signals, and liner network acts with a control signal in the system to overcome the influence on the speed of D. C. motor to load torque. Numerical examples are provided to illustrate the considered system not only has good dynamic and static performances, but also has strong capability of objection to load torque disturbance.
