摘要：

针对座舱压力调节系统的非线性和参数时变特性，提出了模糊滑模变结构控制方法. 模糊滑模变结构控制算法保持了模糊控制器不依赖系统模型的优点，对参数变化和外界干扰等不确定性因素具有较强的鲁棒性，同时能柔化控制信号，减轻或者避免了一般滑模控制的抖动现象. 研究表明，模糊滑模变结构控制器与经典PID控制相比，具有超调量
小、稳态误差小、响应速度快、扰动抑制能力强等优点，试验结果证明了该方法对座舱压力调节系统控制的有效性.

关键词: 座舱压力调节系统, 模糊滑模变结构控制, 非线性

Abstract:

Based on the nonlinear and time varying parameter of the cabin pressure regulating system characteristics,
a control strategy of fuzzy sliding mode variable structure control is proposed. The fuzzy sliding mode variable structure controller keeps advantages of unreliable system mode of fuzzy controllers, and has the additional
advantages of strong robustness to parameter variation and disturbance, elimination or avoidance of chattering phenomena of sliding mode controllers by using softening control signals. Experiment results show that the proposed method can improve the system’s dynamic response and reduce steady-state errors, and is invariant to disturbances compared to PID controllers.

Key words: cabin pressure regulating system, fuzzy sliding mode variable structure control, nonlinear
