摘　　要：目的研究一种用于连续随机控制系统的多指标综合技术．方法利用线性矩阵不等式方法实现系统状态反馈将闭环极点配置在指定区域中，同时使闭环系统满足Ｈ∞指标和稳态协方差约束．结果得到了状态反馈应满足的条件及求取状态反馈阵的计算方法．Aim\ To study the design of multiple objective synthesis approach for linear continuous stochastic systems. Methods\ Using Linear Matrix Inquality to design the state feedback law such that the closed loop systems satisfy the H ∞ constraint, pole placement and steady state covariance assigment simultaneously. Results\ Obtained the conditions that the state feedback meets and proposed the algorithm for finding the state feedback matrix. Conclusion\ The proposed method is verified by numerical examples and the results show that the aproach is available.
