摘要
以双伺服电机组成的同步运行系统为研究对象,建立了系统的数学模型。基于线性二次型调节器(LQR)的性能指标设计了最优控制器,并采用转矩扰动观测器作为前馈补偿控制器以克服突加负载对系统的影响。在MATLAB/Simlink环境下建立仿真模型,仿真结果验证了系统良好的同步运行性能和抗干扰性能。
With the synchro- running system composed by double servo motor taken as a object,the system model was established. In this paper,an optimal controller was designed based on the approach of linear quadratic regulator（ LQR）. At the same time,a feed- forward controller used torque disturbance observer was described to overcome the effects of sudden load on the system. Then the mathematical model was built with MATLAB / Simlink. The simulation results show the good performance of synchro- running and anti- interference.
