摘要:

研究2级控制系统中量化状态观测器的设计方法.对设计的控制系统的输入、输出信号进行量化,使得这些数据可以在网络环境中传输.研究对量化后的数据经过非完美的频道传输时造成的数据损失的处理方法.设计状态观测器,对控制系统的各个信息进行估计.设计控制器,能够根据状态观测器输出的估计值,控制2个致动器协调工作,成功地实现了2级控制.在实验平台dSPACEDS1103上对所设计的2级控制系统进行验证,实验数据验证了本文提出的2级控制器设计方法的有效性和可行性.

Abstract:

The method of designing the quantized state estimator for dualstage control system was aralyzed. The input and output signals were quantized to transmit in network environment. The method processing the quantized signals which lose during the unreliable channel was analyzed. Then the state estimator was designed to estimate the information of control system. The controller was designed to control two actuators to coordinately work according to the estimated value from the state estimator, and the dualstage control was realized. An experiment on dSPACEDS1103 illustrates that the approach to design dualstage controller is effective and feasible.
