摘要
基于某航空用二冲程活塞式发动机的非线性模型,利用扇形非线性特性得到了发动机模糊Takagi-Sugeno(T-S)模型;基于该T-S模型,采用系统增广的方法研究了无静态误差转速控制器;设计中考虑了鲁棒H∞性能,使得该非线性系统的模糊控制器具有较好干扰抑制性能,并在Lyapunov稳定性理论基础上建立了该系统渐进稳定的线性矩阵不等式条件;最后通过系统仿真算例验证了所设计控制器的有效性.
The engine Takagi-Sugeno(T-S) models were obtained by sector nonlinearity based on the nonlinear two-stroke internal combustion engine model.A nonlinear engine speed controller was researched,and the system augmented method was used for the design of control algorithm without steady-state error.By considering the robust H∞,a disturbance rejection controller design for the T-S fuzzy models was presented.The stability conditions were derived using Lyapunov approach,and the problems were formulated as linear m...
