[Abstract]:With the development of the technology of measurement while drilling, the amount of data needed to be transmitted is increasing, so it is necessary to improve the transmission rate of the data while drilling. Mud continuous wave pulse generator with its high transmission rate, good reliability and strong anti-jamming ability has become an important development direction of data transmission system while drilling measurement. The design of motor drive system is the core of mud continuous wave pulse generator. The main work of this paper is the design and realization of permanent magnet synchronous motor control and drive circuit. Firstly, the working principle and rotor control method of mud continuous wave pulse generator are introduced, and the magnetic field oriented control strategy and space vector pulse width modulation algorithm are deduced in detail. It lays a foundation for fast control of angular displacement and angular rate of permanent magnet synchronous motor (PMSM). Secondly, the design of PMSM drive system is introduced in detail, including the design of power management module, the design of digital control system based on TMS320F28335, the design of three-phase inverter circuit and its driving circuit. Auxiliary circuit design and hardware and software anti-interference design, the system designed short-circuit protection, voltage transient protection, over-current protection, over-voltage protection, under-voltage protection, over-temperature protection and other protection circuits to ensure the robust operation of the drive system. Then the software of the drive system is introduced in detail, including the field oriented control algorithm, PID regulator, space vector pulse width modulation algorithm, PWM module configuration, current sampling and processing program design, position feedback program design. The program of fault detection and protection and the design of SCI communication are designed, and the host computer software for the debugging of permanent magnet synchronous motor is programmed by using LabVIEW2014 of NI company. Finally, the experimental platform of mud continuous wave pulsator is built and the ground hydraulic cycle experiment is carried out. The experimental results show that the driving system designed in this paper can run stably, and the upper computer and lower computer can work together well.
