The two-cylinder drive is one of many commonly used mechanical drive forms. Its synchronous control accuracy determines the movement accuracy of the working machinery. The paper established the mathematical model for the two-cylinder electro-hydraulic servo synchronous drive system, and revealed that the two-cylinder horizontal electro-hydraulic synchronous drive system has the cascade form of the linear system with the nonlinear system. Taking the band sawing machine and the broaching machine as the application object, the paper analyzed their compositions and synchronization CNC systems. Aiming at the dual-cylinder drive form for the broaching machine, the IPSO-PID synchronous controller of the two-cylinder system was designed. Through the digital simulation and actual testing, the results show that the IPSO-PID synchronous controller is faster in the tracking response speed and better in the synchronization performance than the conventional PID synchronization controller.

Abstract The paper presents idea and practical implementation of a medium voltage synchronous drive with a voltage source inverter in the stator circuit and a microprocessor controlled unit for excitation supply. Construction of both devices was presented, and methods of their cooperation were described. Selected start-up methods of large power synchronous motors were presented. Exemplary realization was discussed. Measurement results of the direct full-voltage start-up and frequency start-up of a real 1.25 MW 6 kV fan drive system were compared and discussed.

With the frequency converter for driving belt conveyor, the synchronous control of torque and speed for the belt-drive unit can be achieved and the start-up characteristics of belt conveyor can also be improved. This paper uses two methods for achieving synchronous drive of belt conveyor, one is synchronization through master-slave control of frequency converter itself, the second is adding external algorithm implemented by PLC systems. This article describes a variable-frequency adjustable-speed drive system used for long distance belt conveyor in mine main inclined shaft or ground. This frequency conversion device and system can be applied to the adjustable-speed drive process of constant torque load for conveyor.

Electric vehicle (EV) is the greatest potential production of new energy vehicles. It plays a very important role in the area of energy conservation and reduction of pollutant emissions. In order to accelerate EV industrialization, the paper proposed a motor design method,which need to combine the automobile theory with the design permanent machine (PM). The paper considered the vehicle’s dynamic parameters, defined the motor’s basic parameters and designed the dimensions of electromagnetic structure, and then analyzed the field of the motor using finite element method (FEM). The paper firstly presents that drive motor’s design should consider two respects: one is the vehicle and another is the drive motor. In view of length of paper, only the no-load field analysis was proposed in this paper. The effectiveness of the proposed method is verified by the analysis results.
