多约束自适应控制在航空发动机自动试车中的应用
AEROENGINE TEST AUTOMATION OF ADAPTIVE CONTROL WITH RESTRAINTS
-
摘要: 对采用模型参考自适应控制方法设计带有多项约束条件的航空发动机试车自动试车控制系统进行了研究。仿真结果表明:这种控制方法不仅对被控对象含有的非线性环节,以及被控对象参数在较大范围内的变化具有较好的适应能力。而且当约束条件超限时,通过对控制器参数的调整,可使主控参数和约束条件参数均满足相应的控制指标。Abstract: An automatic control system of aeroengine test has been designed,based on the method of model reference adaptive control with restraints.According to its simulation results,this method has good adaptability when the controlled member contains non-linear elements or the controller member varies in a large range.The simulation results also show that ,the controlled system still has satisfactory performance index by regulating the controller's parameters,even if the restraints are out of limits.
