Abstract. Besides different field-weakening control algorithm during accelerating and decelerating process of permanent magnet synchronous motor, the control system proposed in this paper also combined Maximum torque/ampere control with field-weakening control methods. It not only satisfied the large torque and wide speed range requirement which was put on drive system by vehicle, but also improved the reliability of drive system. Modeling and simulation work of the drive system are also done with MATLAB, simulation results proved that the control system proposed in this paper is effective.

The priority valve is considered to be one of the critical parts of the hydraulic system used in mining equipment. This article analyzes the dynamic performance of a hydro-motor drive system using priority valve through system modeling and simulation. A typical hydraulic system of a mining equipment is considered for the analysis, where a stable source of flow is supplied to two hydro-motors through priority flow divider valve. Bondgraph simulation technique is used for the modeling of the complete system, which is validated experimentally. The influences of some key parameters on the transient response of the system have been studied through simulation. The work presented in this article forms the basis idea for the design and optimization of the priority flow control valve for a given application.

Analysis And Design

This paper focus on various loading conditions onthe Permanent Magnet Synchronous Motor and its application using field oriented control technique. Constant torqueapplication irrespective of speed isalso presented. This technique helps in lift and belt conveyors handling constant weight of material per unit time, in pumping and compressing and electric locos. Results of simulation shows that proposed system has high acceleration and deceleration rate with vector control,overall quick and dynamic response as well as excellent controlling ability. The vector control is a excellent technology for analysis and design of PMSM drive system. It provides designing and debugging for practical drive system. Modeling and different kinds of Permanent Magnet Synchronous Machines are studied and Simulation is carried out in Matlab and performance is studied at different operating conditions.
