一类不确定非线性系统的最优控制

Optimal Control of a Class of Uncertain Nonlinear Systems

应用非线性系统精确线性化方法，将一类满足一定条件的不确定非线性系统最优控制问题变换成一种参数不确定线性系统的二次型最优调节器问题，从而求得原系统的最优控制．设计例子及仿真验证了本文方法的正确性．

With the exact linearization method, the optimal control problem of a class of uncertain nonlinear systems satisfied certain conditions is transformed into the quadratic optimal regulator problem of a kind of linear systems with uncertain parameters. Hence, the original optimal control problem is at last solved. A designing example and its simulation results verify the correctness of the method provided in this paper.
