| 摘 要： | 介绍了现有LQG控制算法特点,提出了基于全状态反馈的主动序列最优控制律,与现有LQG控制算法相比序列最优控制算法增益矩阵具有时变的特点。结合一栋五层基础隔震框架结构,对该两种控制方法在传感器正常工作时和染入噪声情况下的控制效果进行Simlink仿真分析,仿真结果表明序列最优控制算法的总体控制效果优于LQG控制算法,且序列最优控制算法具有良好的鲁棒性能。

| Abstract: | The characters of Linear Quadratic Gaussian (LQG) control algorithm were introduced and the active Sequential Optimal Control (SOC) algorithm was proposed based on the full states feedback. Compared with LQG control algorithm,the gain matrix in SOC control algorithm had the feature of time variation. A five-story base isolated building frame structure was used to evaluate the control effect in the case of sensor normal working and sensor contaminated with noise by Simlink simulation. Simulation results show that overall control effect of SOC is advantageous over that of LQG and SOC has good robustness. |
