摘　　要：为了选择与无刷直流电动机匹配的调速控制方式,采用了基于可编程片上系统技术的有限状态机分析法.对构建调速控制信号的几个关键环节,如转子空间位置信号调理,脉宽恒定而周期跟踪转速的PWM波形发生器以及控制定子电流正、反向与换相的主控信号等,进行了波形描述和时序分析,并完成了相应数字硬件的设计.为系统的综合设计与实施提供了方案流程,硬件配置和参数设定方面的参照基础.In order to choose a control mode to match Brusless DC Motor,the analytic method of finite state machine based on the system on programmable chip was adopted.For some key units in composition of control signals,like signal processing of rotor space position,PWM signal generator with constant pulse width and variable cycle,and main dominant control signal for switching current in windings and so on,the waveforms and sequences of signals were described and analysed.The correspondent design of digital hardware was completed.The results provid some references in designing charts and parameters.
