| 摘 要： | 环己烷无催化氧化过程具有非线性、多变量耦合、大时滞等特点，使用常规比例积分微分(PID)控制方案无法达到理想的控制性能。提出了一种区间二型模糊免疫PID控制器，其本质上是一种基于免疫PID的非线性控制器，利用区间二型模糊逻辑系统来逼近免疫反馈律中的非线性函数，以提升控制器处理和逼近复杂不确定非线性系统的能力。将所提出的控制器应用于环己烷无催化氧化温度控制系统，仿真结果表明该方法是有效的。

| Abstract: | The non-catalytic oxidation of cyclohexane has the characteristics of nonlinearity, multi-variable coupling, large time delay, etc., and the ideal control performance cannot be achieved by using the conventional PID control scheme. In this paper, an interval type-2 fuzzy immune PID controller is proposed, which is essentially a nonlinear controller based on immune PID. The interval type-2 fuzzy logic system (IT2FLS) is used to approximate the nonlinear function in the immune feedback law, so as to improve the ability of the controller to deal with and approach complex uncertain nonlinear systems. Finally, the proposed controller is applied to temperature control system for uncatalysed oxidation of cyclohexane, and the simulation results show that the method is effective. |
