摘要
提出非线性多变量受控对象的非线性降维观测器(NRO)的一般设计理论 ,从而使 L uenberger线性降维观测器成为其特殊形式。用此方法重构单机 -无穷大母线输电系统同步发电机的功角 δ(t) ,可得到一个非常简单、性能良好的一维 δ-观测器。数字仿真结果表明它具有响应快 ,跟踪力强 。
General design theory for nonlinear reduced order observers (NRO) for forced nonlinear multivariable plants was proposed, with the Luenberger linear reduced order observers as just a special form of the general model. The method was used to reconstruct the power angle δ(t) of a synchronous generator infinite bus power system to develop a nonlinear first order observer with very simple structure and good performances. The digital simulation results show that fast response, good traceability, wide dynamic stability region and ideal closed loop responses can be achived.
