发电机自适应Terminal滑模励磁控制

建立了单机无穷大系统的励磁控制数学模型,设计了一种自适应Terminal滑模励磁控制器。通过在滑模面加入非线性函数,使得误差能够快速收敛,从而取得良好的控制效果。同时考虑了系统中存在未知上界的不确定扰动,在设计中加入了自适应环节,实时估计扰动上界,从而使控制器具有较强的鲁棒性。根据李亚普洛夫理论证明了所设计控制系统的稳定性。仿真结果表明,无论是小扰动还是大扰动下均能有效提高系统稳定性,维持机端电压,效果优于自适应逆推滑模励磁控制。

Adaptive Terminal Sliding Mode Controller of Generator Excitation

A mathematical model of single machine infinite bus system excitation control is established. An adaptive terminal sliding mode excitation controller is designed. By adding non-linear function in the sliding surface,the convergence of error is sped up to achieve good control effect. Considering the uncertainties of disturbances,an adaptive identification of upper bound is designed,so that the controller has strong robustness. According to the Lyapunov theory,stability of this control system is proved. Simul...
