| 摘 要： | 数据总线传输方案能够有效克服传统通信的弊端,但由于信息传输分时复用通信总线,系统时延不可避免。时延不但会降低网络控制系统的控制性能,而且还是引起系统不稳定的潜在因素。从网络时延这一问题出发,对网络控制系统的建模方法进行了分析研究,并基于此提出利用模糊控制来补偿系统时延影响。该方法通过模糊控制调节PID控制器输出,从而改善系统性能。最后通过仿真实例验证了上述方法的有效性。

| Abstract: | The bus transmit scheme can efficiently simplify the system structure,overcome the shortcomings of traditional communication,and increase the reliability.However,the time-sharing multiplex communication bus used in information transmission will inevitably introduce delays,which can degrade the performance of control systems and even destabilize the system.Based on the analysis of modeling methods,fuzzy controller was used to compensate for the influence of delay.The PID control signal was modulated by fuzzy... |
