摘要
直流调速系统广泛采用转速、电流双闭环调节回路,但负载转矩和转速状态变量很难通过安装仪表来进行测量。通过状态观测器,即状态空间理论中输入、输出变量,来对这两个变量进行估计,实现扰动补偿。通过最优估算法来对初始状态空间进行改进,形成全阶状态观测器。
Rotation rate and current double closed-cycle adjustment loop are widely applied in the direct current adjustment system, but it is difficult to measure the load torque and rotation rate state variable by installing instruments. The state observer can realize the disturbance compensation by estimation of the two variables, namely, input and output. The primary state space will be improved with optimal estimation method into the full-step state observer.
