动态输出反馈D-保性能控制是线性系统的重要控制方法。针对一类由动态输出反馈D-保性能控制器构成的闭环线性系统,提出了用硬件冗余方式解决系统传感器信号增益误差问题。考虑传感器信号增益误差模型,提出了传感器信号增益误差的容忍区间,容忍因子和硬件冗余度的概念。通过求解具有线性矩阵不等式(linear matrix inequality,LMI)约束的优化问题,给出了传感器信号增益误差的容忍区间,容忍因子和硬件冗余度的求解算法。工程师可以根据传感器各通道硬件冗余度的大小进行传感器的硬件冗余设计。一个某型飞机着陆过程的实例仿真说明了所提方法的有效性。
Dynamic Output Feedback D-Guaranteed Performance Control is an important control method for linear systems. For a class of closed-loop linear system composed of dynamic output feedback D-guaranteed performance controller, the problem of gain error of system sensor signal is solved by hardware redundancy. Considering the gain error model of the sensor signal, the concept of tolerance interval, tolerance factor and hardware redundancy of the gain error of the sensor signal is proposed. By solving the optimization problem with the linear matrix inequality (LMI) constraint, the tolerance interval, tolerance factor and hardware redundancy of the gain error of the sensor signal are given. Engineers can be based on the sensor hardware redundancy of the size of the sensor hardware redundancy design. An example simulation of a certain aircraft landing process shows the effectiveness of the proposed method.
