摘要
针对飞机座舱导光板自动调光控制方法进行研究,提出一种导光板自动调光系统的滑模控制方法,完成系统设计、受控对象建模及滑模控制器搭建,借助Matlab对控制率进行仿真,对比控制器参数的不同取值对应的系统阶跃响应、跟踪特性,并优化控制器参数。结果表明,该系统响应速率快、跟踪精度好,能根据光环境照度变化调整导光板能耗,实现稳定导光板字符对比度、降低导光板能耗的控制目标,有利于提升机组人员工作绩效。
In this paper,the control method of light panel auto-dimming in cockpit is studied,and a sliding mode control method for auto-dimming system is proposed,the design of control system,modeling of controlled object and construction of sliding mode controller are completed.By using Matlab,the control rate is simulated,comparing the system step response as well as the tracking accuracy with different parameters,and optimizing the controller parameters.The results show that the control system has a fast response rate,good tracking accuracy,and can adjust the power consumption of light panel according to the change of the illumination of ambient light,thus achieving the control objectives of stabilizing the character contrast,reducing the power consumption of light panel,and improving the crew’s work performance.
