由于作为控制元件的调整型液力偶合器的动态特性非常复杂 ,直接影响了整个系统(如渣浆泵调速型液力偶合器调速液位控制系统 )的动态过程 ,使得系统的调节具有严重的非线性 ,系统模型具有不确定性。为此本文提出采用模型参考自适应 (MRAC)与PID复合控制的方法来解决上述问题。与常规自适应控制法相比该方法大大简化了系统设计 ,大量的仿真和实验研究也证明了此方法是有效和实用的。
Because the dynamic characteristics of the adjustment type fluid coupling as the control element are very complicated, it directly affects the dynamic process of the entire system (such as the speed control fluid level control system of the slurry pump speed governing fluid coupling), so that the adjustment of the system has Serious non-linear, system model with uncertainty. Therefore, this paper proposes to adopt the method of model reference adaptive (MRAC) and PID compound control to solve the above problems. Compared with the conventional adaptive control method, this method greatly simplifies the system design. A large number of simulation and experimental studies also prove that this method is effective and practical.
