摘要
针对网络控制系统中普遍存在的信息量化问题,采用基于模型的控制策略,研究了一类网络控制系统的稳定性.在考虑均匀量化的影响下,对于不同的初始量化误差,分别讨论了系统的稳定性,并给出了保证系统全局指数稳定的充分必要条件以及系统的稳定域范围.仿真结果验证了所得结论的正确性.
The stability of a class of networked control systems is considered by adopting model-based control strategy in view of the quantization effect which exists generally in networked setting. Necessary and sufficient conditions for system to be globally exponentially stable and the stable regions of the system are presented under different initial quantization errors. Simulation examples results show the correction of the conclusion.
