“…Chen et al 4 had established a six-degree-of-freedom high-speed elevator car model with diagonal structure and proposed a model-based hybrid H 2 /H ∞ optimal control strategy, introducing free matrix into the control strategy to improve the robust stability of the elevator car system. Zhang et al 5 proposed a semi-active guide shoe variable domain fuzzy control method for magnetorheological dampers based on firefly algorithm and backpropagation (FA-BP) algorithm fuzzy neural network (FNN). Firstly, using the raw data of MR dampers collected from experiments, a nonparametric model of MR dampers based on FNN system was established, and then a variable domain fuzzy main controller was proposed to control the input current of MR dampers.…”

The high-speed elevator car is subject to violent horizontal vibration due to the wind pressure generated by the ventilation hole of the elevator rapid operation, improper adjustment of the gap and steps at the joint of the elevator car guide rail, pitting corrosion or wear on the guide surface of the guide shoe, inadequate installation and adjustment of the guide shoe or guide rail and so on. Aiming at the problems of poor transient convergence and real-time performance, low control accuracy and stability of the existing active control algorithm for the horizontal vibration control variables of the elevator car system, a transient response feedback control strategy with specified performance is proposed in this paper. Firstly, a six degree of freedom elevator car system model is established, and the state space equation is constructed based on the linear fractional transformation algorithm; Secondly, a class of preset transient performance function is introduced to construct the convergence boundary in advance to ensure that the system control variables are strictly constrained within this boundary, and the stability of the transformed variables is ensured by equivalent transformation; Finally, four different control methods including passive control, H2/H∞ control, PID control and transient response feedback control proposed in this paper are compared and analyzed by using MATLAB under two typical guideway excitation. The simulation results show that the proposed transient response feedback control strategy reduces the root mean square value and maximum value of the horizontal displacement acceleration of the elevator car system by more than 81%, effectively suppresses the horizontal vibration of the elevator car, and ensures the transient and steady-state performance of the elevator car system.

The failures of steel guides can excite complex and intense transverse oscillations of hoisting containers in the mine hoisting process. The present paper mainly contributes to reveal the response characteristics of the transverse oscillations of mine conveyances excited by various faults such as interface misalignment, local bulge, orbital gap, bending deformation, and orbital tilt. First, a rigid-flexible coupled virtual prototype model between the conveyance and the steel guide was established. Subsequently, the vibration response characteristics of the container under various single and coupling excitations were simulated and analyzed. Eventually, a new type of roller cage shoe with a magnetorheological damper was put forward to decrease the transverse impact responses. Based on the hyperbolic tangent model of magnetorheological dampers, a semiactive fuzzy PID method was studied to explore the vibration suppression of the container. The results showed the fuzzy PID method can play a good role in the vibration reduction. This paper can give a fine scheme for the virtual simulation and semiactive vibration control of the mine hoisting 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 FSADR control method designed in this paper can effectively suppress the horizontal vibration generated during the operation of high-speed elevators.
