摘要/Abstract

摘要： 通过航空发动机控制系统的非线性数字仿真,发现对于同一控制变量制定的复杂控制计划不能由多个控制器实现,这个问题可以通过控制通道的增益匹配得到解决。给出了频域和时域的两种控制通道增益匹配的方法。仿真表明,经过控制通道的增益匹配能够实现所制定的复杂控制计划,同时可以大幅度地简化控制系统的控制逻辑,使得所设计的控制系统更具工程实用性。

Abstract: Numeric simulation using nonlinear plant model on the aeroengine control system shows that the complex control sheme referring to one control variable can not be realized by multi-controllers.The problem arised may be solved by channel gain scheduling.Channel gain scheduling methods on frequency and on time region are described in detail.The scheduled gains are put back into the nonlinear control system simulation model.Simulation shows that the complex control scheme is realized by the channel gain schedule program.Simultaneously,the complexity of the control logic of the control system is greatly predigested to make the control system more practicable in engineering.

Key words: Aircraft engine control~+;Gain scheduling;Aerospace propulsion system~+;Numerical simulation.
