| 摘 要： | 基于Ｇａｕｓｓ－Ｈｅｒｍｉｔｅ积分规则,提出了二次型高斯非线性随机控制新方法。该方法克服了传统的线性化方法所导致的“基础结构失真”的缺陷,提高了系统状态的估计精度和最优控制策略近似解的精度,同时又具有较好的实时性。通过高超声速飞行器纵向运动控制的仿真,验证了该方法的有效性。

| Abstract: | In this paper, a new approach is given to the nonlinear stochastic control for Quadratic Gaussian Problem an the base of the Gauss - Hermite integration. This approach avoids the fault of "basic structure distortion" caused by conventional linearization, increasesthe estimation precision of system states and approximate solution precisian of the optimal control, and has good real time characteristic. Simulation result for longitudinal modes of hypersonic vehicle proved this approach effective. |
