| Hydraulic lifting technology is one of the technologies that have been very commonly used in China in recent years.The hydraulic lifting system is mainly composed of three aspects: load-bearing,power and control,and the load-bearing link includes lifting units and the rest of the system to cooperate to achieve high-altitude operations.Adjustment of the lifting process form conversion,commissioning safety of the stagnation phase and the fine tuning of the operating components are critical.At the same time,the technology is also applied in complex construction sites in terms of the principle of backward assembly,aerial connection,and the application of a complete automated centralized control system to ensure the safety and effectiveness of control.The subject comes from the R & D and application of steel formwork operating frame lifting control technology for high-rise buildings,taking multiple lifting units of high-rise buildings as the research object and building unbalanced load steel formwork actuator.Using unbalanced large load lifting technology,the dynamic configuration of the building,the implementation of online adjustment and improve the quality of industrial construction.In the technology of hydraulic hoisting system,due to the limitations of construction technology and safety efficiency and other conditions,it is not only necessary to ensure that the indicators and data of the hoisting meet the requirements,but also to ensure that the hoisting of each hoist is carried out smoothly under the control of load balancing.In the conventional method,the PID control is close to the real-time adjustment and synchronization function,but because the control parameters cannot achieve adjustable effect,resulting in system instability and uncertainty.To address this challenge,this paper adds a fuzzy adaptive controller for master-slave control of the system,and uses a joint simulation method to select hydraulic components through AMESim and a joint detection module for algorithm analysis.Meanwhile,the pressure compensator and variable throttle model in the hydraulic library are selected to build,and the internal parameters between each hydraulic component are analyzed and calculated to ensure that the pressure difference value is within a certain range to control the flow size of the hydraulic pressure and to design.Finally,the simulation results obtained not only reach certain values in terms of operating speed,but also have practical significance in the control system. |
