[Abstract]:Variable speed throttling compound speed regulation is a new hydraulic speed regulation method developed on the basis of variable frequency pump controlled motor hydraulic power drive. It combines variable speed speed regulation with throttling speed regulation. It not only has good energy saving and reliability, but also overcomes the shortcomings of variable speed hydraulic speed regulation system, such as slow dynamic response and poor low speed characteristic. Therefore, it is widely studied. In view of the complex system structure of compound speed regulation, the corresponding control strategy and algorithm must be explored and studied, so as to establish an effective control system. The paper studies the operation mechanism of hydraulic system. The control strategy and fuzzy PID control algorithm are used to design a control system of variable speed and throttling compound speed control system. The test platform is established and the simulation and experimental research of the control system is completed. This paper introduces the basic form and characteristics of hydraulic speed regulating circuit, and expounds the general situation and development trend of variable speed hydraulic technology, electro-hydraulic measurement and control technology and fuzzy control technology. The control strategy and fuzzy PID control algorithm of variable speed throttling compound speed control system are analyzed and summarized. The simulation system is built with AMESim. At the same time, the control part of the system is studied through the joint modeling and simulation of AMESim and Simulink. The controller which follows the compound control strategy and contains the fuzzy control algorithm is designed, and the hydraulic measurement and control system is developed based on the virtual instrument technology and the modular design method. In the part of data acquisition, the measurement architecture of data sampling and restoring and DAQmx is introduced. It uses the method of measuring the width of single pulse to measure the speed of motor. A series of data processing methods are used to obtain the ideal results. In the controller module, the design of digital PID control program and fuzzy controller in LabVIEW is mainly realized. Video monitoring module and network communication module make the information level of the system higher. Using the above established joint simulation system and experimental platform measurement and control system. A large number of simulation and experimental studies have been carried out in this paper. The results show that the pump control motor variable speed throttling compound speed control system is superior to the traditional hydraulic speed control system in terms of control and energy saving. The new compound control strategy and fuzzy control algorithm further improve the control characteristics of the compound speed control system. [67 tables. [9 reference. [64]
