摘要

为了有效控制高速电梯轿厢系统因导轨不平顺性和导轨鞋弹簧阻尼非线性等因素引起的水平振动，提出了一种基于模糊滑模的自抗扰(ADR)控制方法。首先，考虑导靴弹簧阻尼的非线性特性，建立了电梯轿厢系统水平振动动力学模型;然后，将导轨激励和小车的线性和非线性扰动归纳为小车系统的总扰动，并利用所设计的扩展状态观测器进行估计。在此基础上，提出了一种滑模自抗扰(SADR)控制方法，使汽车系统的抗振、抗扰控制具有很强的鲁棒性。针对滑模控制引起的抖振问题，设计了模糊控制方法加以消除，进一步实现了汽车系统水平振动的模糊滑模自抗扰(FSADR)控制。最后利用MATLAB/Simulink进行仿真测试。仿真结果表明，与ADR和SMADR相比，FSADR显著降低了水平振动加速度的均方根值、最大值和A95峰值。因此，本文设计的FSARC控制方法可以有效抑制高速电梯运行过程中产生的水平振动。DOI: 10.61416 / ceai.v25i2.8336

Study on Fuzzy Sliding Mode Active Disturbance Rejection Control Method for Horizontal Vibration of High-Speed Elevator Car System

To effectively control the horizontal vibration of high-speed elevator car system caused by the factors such as the irregularity of the guide rail and the nonlinearity of spring-damping in guide shoes, this paper proposes an active disturbance rejection (ADR) control method based on fuzzy sliding mode. Firstly, considering the nonlinear characteristics of the spring-damping in the guide shoes, the horizontal vibration dynamic model of the elevator car system is established. Then, the guide rail excitation and the linear and nonlinear disturbances of the car are summarized into the total disturbances of the car system, which can be estimated by the designed extended state observer. On this basis, a sliding mode active disturbance rejection (SADR) control is presented, which makes the anti-vibration and anti-disturbance control of the car system highly robust. For the chattering problem caused by sliding mode control, the fuzzy control method is designed to eliminate it, and the fuzzy sliding mode active disturbance rejection (FSADR) control for the horizontal vibration of the car system is further realized. Finally, MATLAB/Simulink is utilized for simulation tests. The simulation results show that, compared with ADR and SMADR, the root mean square value, maximum value and A95 peak value of horizontal vibration acceleration through FSADR are significantly reduced. Therefore, the FSARC control method designed in this paper can effectively suppress the horizontal vibration generated during the operation of high-speed elevators. DOI: 10.61416/ceai.v25i2.8336
