Problems solved by technology

Traditional guide shoes have many shortcomings and cannot meet the needs of linear elevators. The traditional guide system cannot actively suppress and weaken the vibration of the car, and there is friction, which cannot meet the high-speed operation requirements of elevator systems in high-rise and even super high-rise buildings.

Embodiment 1

[0113] The main parameters of the single magnetic levitation guidance system of the linear elevator: the total mass M of the elevator car is 500kg, and the cross-sectional area A of the single electromagnet is 0.05×0.05m 2 , the number of turns N of the single electromagnet winding is 380 turns, and the expected air gap is 0.005m.

[0114] Based on the above system parameters, system simulation conditions: (a) Suppose the equivalent horizontal step disturbance force generated by passengers entering and exiting the elevator car or walking in the car is 2000N, and this disturbance is added at 0.5s to 0.6s; (b) And add a periodic disturbance whose amplitude is 0.5mm, and simulate the system, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 shown. Figure 5 and Figure 6 Shown is based on fuzzy adaptive fractional PI λ D. μ Simulation curves of the air gap and air gap deviation of the x-axis subsystem of the controlled single maglev guidance system. When there are sys...

Abstract

The invention relates to a control method for achieving stable operation of a magnetic suspension guide system of a linear elevator. Fuzzy control and fractional order PIlambdaDmu control are combined, and stable operation of the magnetic suspension guide system of the linear elevator is achieved. The method has the advantages that online adjustment of controller parameters is achieved through fuzzy logic, so that response speed of the system is higher, and steady state precise performance of the magnetic suspension guide system is improved. On the basis of PIlambdaDmu control, a fuzzy self-adaptation controller is designed, fuzzy control quantity takes the place of equivalent control, and accordingly quick and stable operation of the magnetic suspension guide system of the linear elevator is achieved.

Description

technical field [0001] The invention belongs to the technical field of elevator control, and in particular relates to an operation control method of a magnetic levitation guide system for a linear elevator. Background technique [0002] Today more and more high-rise buildings are built in Asia and other parts of the world, such as Taipei International Finance Center, Kuala Lumpur Petronas Twin Towers. The Burj Khalifa in Dubai, United Arab Emirates, has a total of 160 floors and an overall building height of 828 meters, 320 meters higher than the Taipei International Financial Center. This is the first building in human history that exceeds 800 meters. This type of architecture presents a formidable challenge to elevator system design engineers. Due to the rise of high-rise buildings, higher requirements are placed on the elevator system. The focus of high-rise buildings is on the improvement of the transportation system. At the same time, there is also a technical thresho...
