|
摘要
针对异步电动机速度控制系统中的不确定性负载问题,本文设计了新型自适应反步控制器,实现异步电动机高性能转速跟踪控制。通过选择合理的Lyapunov函数及稳定函数,给出自适应反步控制算法,分析了整个控制系统的稳定性。在递归设计中首次出现不确定性负载时,设计了负载的自适应律,得到新型自适应负载转矩观测器,精确估计了不确定性负载转矩。仿真结果表明,本文设计的新型自适应负载转矩观测器,实现了不确定性负载的在线精确估计。与矢量控制方法相比,该控制策略的转速响应更加迅速,快速消除了负载扰动对转速的影响,具有良好的应用前景。
Aiming at the problem of uncertain load in induction motor speed control system,this paper designs a novel adaptive backstepping controller to realize high performance speed tracking control of induction motor.By selecting reasonable Lyapunov function and stabilizing function,an adaptive backstepping controller is given,and the stability of the whole control system is analyzed.When the uncertain load appears for the first time in the recursive design,the paper designs the adaptive law of the load and obtains a new adaptive load torque observer to accurately estimate the uncertain load torque.The simulation results show that the proposed adaptive load torque observer can accurately estimate the uncertain load on-line.Compared with the vector control,the proposed control strategy has faster speed response and can quickly eliminate the impact of load disturbance on the speed.This work has a good application prospect.
