本文讨论了一类由Brown运动驱动的扩散项中同时具有控制和干扰信号的非线性随机系统的H∞控制问题.由二次不等式出发,结合配方法的原理得到一类含参数Hamilton-Jacobi方程(HJE),在此基础上分别得到了时域无限和时域有限的基于状态反馈的H∞控制.最后,结合具体例子讨论了这类含参HJE的求解问题.
This paper discusses the H∞ control problem for a class of nonlinear stochastic systems driven by Brownian motion with both the control and exogenous disturbance entering the diffusion. By an inequality of quadric form, an approach to solving Hamilton-Jacobi equations(HJEs, for short) with parameters is presented, and both infinite and finite horizon nonlinear stochastic H∞ designs are also developed. Finally, we discuss the solvability of such HJEs with parameters.
