Abstract:This paper brushless dc motor from the structure and the working principle, a detailed explanation of brushless dc motor in the conduction, free-wheeling mutation three different state equation and the voltage of brushless dc motor of the torque characteristics and its dynamic mathematical model to establish of brushless dc motor transfer function.
Based on the analysis of brushless dc motor current and speed adjustment principle was put forward on the basis of current and speed control scheme, introduced the theory of classical control PID control. According to the simulation control system theory to the digital conversion, completed the design of the system software, perfect the PID control system. PWM interrupt and respectively in 1 KHZ interrupt realized the current loop and speed loop, finish at the same time two loop transfer. According to the function demand, perfect the function of the realization of the program.
Finally, the performance of the controller and various functions of the strict test, the test are the graphics, data and results, test show that the controller good reliability, low cost, in line with the development of the product requirements
