摘要
对于航空发动机这样复杂的系统,经典的PID算法难以对其实现良好控制。灰色系统理论是处理不确定量的一种有效途径。它需要信息少,通用性好,计算方便。针对航空发动机难于建立精确数学模型的特点,采用灰色控制理论与PID控制相结合,实现对PID参数的最佳整合。并且对某型航空发动机进行了全包线内的数字仿真。仿真结果证明了其在航空发动机控制中的可能性。
Due to its simplicity, utility and easy application, PID controller is used largely in classical automation systems. However, the performance of the controller can not satisfy complicated nonlinear systems such as aircraft engines. It is very difficult to formulate accurate models for aircraft engines. This problem can be solved on the basis of the grey theory. In this paper, two control method of grey control and PID control was combined in this paper which was used to revise the parameter ofPID. Finally, the simulation results indicate that the designed integrated controller has good performances.
