  2. Secondly, the main stuctures of the software and hardware parts of the control system are introduced. principles and realization of the main functional blocks of these two parts are illuminated. on the hardware of the system, parts of control circuit and the design and debugging of peripheral circuits are discussed thoroughly. based on the hardware circuit, the software is programmed with assembly language. dual close loop vector control weth feedback of speed and current are realized. the flow charts of main programme and pwm interrupt service routines are given. the important control strategies of vector control pmsm such as current sensint and scaling, speed sensing and scaling, bector co - ordinate transformation, generation of sine and cosine, pi regulators, svpwm vector modulation and so on are all accomplished in the pwm interrupt sevice routines. in order to unite all the variables in the programme, scaling is used
