摘　　要：增益调度是解决非线性的一种有效方法,针对座舱压力调节系统具有非线性、时变等特性,通过连续增益调度使系统控制参数达到全局优化,解决了一般增益调度参数只是局部优化的问题。试验研究表明,与单纯PID控制器相比,连续增益调度使系统动态性能有较大提高,稳态误差大大降低,证明了该方法对座舱压力调节系统大范围控制的有效性。Gain scheduling is a valid algorithm to treat nonlinear problem. In order to solve nonlinear and time varying of cabin pressure regulating system, continuous gain scheduling algorithm was used to globally optimize control parameters and the problem that only local optimum control parameters can be gained by normal gain seheduling algorithm was avoided. Experimental results show that compared with single PID algorithm, the response of cabin pressure regulating system is increased and stable error is decreased using continuous gain scheduling, and this new algorithm is valid to regulate cabin pressure in larger range.
