摘要
飞机进气道调节系统使用数字式控制器与进气道斜板位置传感器,形成斜板控制指令,改变进气道斜板开度,使进气道和发动机流量匹配。基于进气道调节系统的工作原理及系统结构,利用Simulink建立仿真模型,分析进气道调节系统数字式控制器的控制策略,提出基于线性叠加原理的调节电压输出控制策略,并通过进气道斜板的阶跃响应,验证采用此控制策略的数字式控制器的超调量和响应时间可以满足进气道调节系统的动态特性需求。
Aircraft intake control system uses digital controller and intake ramp position sensor to form ramp control command, change the opening of intake ramp, and make the intake and engine flow match. Based on the working principle and system structure of the intake control system, a simulation model is established by using Simulink, and the control strategy of the digital controller of the intake control system is analyzed. A control strategy of regulating voltage output based on the linear superposition principle is proposed. The number of the control strategy is verified by the step response of the intake ramp plate. The overshoot and response time of the word controller can meet the dynamic characteristics of the intake control system.
