CPLD + CAN总线改造，采用CPLD 进行编程，实现移相编码和电机功率输出， CAN总线进行数据通讯，使各节点独立工作又集中管理，实现集散控制。节点电机调速方案中，微控制器选用8位高性能微转换器ADμC812，逻辑与伺服控制采用全数字化方式，晶闸管主电路触发器选用ALTERA公司的 EPM7256S CPLD来完成。-CPLD+ CAN bus transformation, using CPLD for programming, coding and phase motor power output, CAN bus for data communication, so that each node independently and focus on management, distributed control. Node in the motor control program, use 8-bit high performance microcontroller micro-converter ADμC812, logic and all-digital servo control mode, the main thyristor trigger circuit used ALTERA company EPM7256S CPLD to complete.
