“电子鼓手”的计算机控制系统实现

Implementation of Electronical Drummer's Computer Controlling System

在解释了“电子鼓手”中鼓机控制系统组成和工作原理之后,详细描述了如何通过网络方式进行多个鼓机之间控制信息传输的基本方法,进而介绍了使用CPLD芯片所完整实现的无刷直流电机控制电路,特别是如何进行电机转子位置的检测和确定、转速的控制与调节等具体实现方法。从而,使得普通无刷直流电机具有了伺服电机,甚至是步进电机的运行效果,并作为“电子鼓手”的驱动系统而完成了多种不同的功能。在此基础之上,亦顺利地完成了基于CAN总线的多电机协调控制的相关研究。

After the describing the archtecture and pranciple of ＂electronical drummer＂, the basic way of the transmission of controlling message is described in detail among the drummers by the CAN network. The key problems such as detecting the position of the roters of the motor, the truning speed control, are solved successfully. Then, the controlling circuit based on CPLD is estabhshed, so the BLDC motors under such control can even perform as precisely as that of step motor. In this case, the BLDC motors drive the drummers to complete complex performances.
