对一类非线性系统进行平衡工作点参数化,得到调度(SCHEDULING) 参数线性化方程。在此基础上,利用线性VSC 理论设计调度参数化的局部线性控制器。为了减少某一状态下控制器对调度参数实际值的影响,在控制器中引入调度变量修整项。将所得结果用于飞行控制系统,设计出飞机纵向通道的调度参数化控制器,数字仿真验证了控制器的控制性能,结果良好。
For a class of nonlinear systems, the working point of the equilibrium is parameterized to obtain the linearized equation of the SCHEDULING parameter. On this basis, the linear VSC control theory is used to design the parameterized local linear controller. In order to reduce the influence of the controller on the actual value of the dispatching parameter in a certain state, the dispatching variable of the dispatching variable is introduced into the controller. The results are used in the flight control system, and the scheduling parameterized controller of the longitudinal channel of the aircraft is designed. The numerical simulation verifies the control performance of the controller and the result is good.
