研究了网络控制系统中遥感器A/D转换器的最优误差反馈滤波器。它示出,如果从量化误差到感兴趣的输出的传递函数具有最小相位,则其逆是最优误差反馈滤波器的任何种类的误差范数。对于一般的线性时不变系统,误差反馈滤波器的设计可以转化为一个优化问题,并可以用数值方法求解。设计实例验证了该方法的有效性。
Optimal error feedback filters for A/D converters of remote sensors in networked control systems are studied. It is shown that if the transfer function from the quantization error to the output of interest has a minimum phase, then its inverse is the optimal error feedback filter in terms of any kind of norms of errors. For general LTI systems, the design of error feedback filters is formulated as an optimization problem, which can be numerically solved. A design example is provided to demonstrate the effectiveness of our proposed method.
