【摘要】 提出了一种基于单纯形法的航空发动机PID控制参数寻优方法。建立了航空发动机PID控制系统的数学模型;以时间乘以误差绝对值积分(ITAE)的性能指标作为寻优的目标函数;利用临界灵敏度法进行PID参数初始整定,并将整定的PID参数作为寻优初始值,再利用单纯形法进行航空发动机PID控制参数寻优。仿真结果验证了本方法的有效性和合理性。更多还原

【Abstract】 An optimization method of PID controller parameters for aircraft engine based on simplex method was proposed.A simulation model of PID control system for aircraft engine was developed.A performance index of integral of time-weighted absolute error(ITAE) was presented as an objective function of optimization.PID parameters were tuned firstly by using the critical sensitivity method and the parameters tuned by this method were used as the initial values of optimization.Simplex method was applied to optimization of PID controller parameters for aircraft engine.Simulation results validate the rationality and validity of the optimization method.更多还原
