用CPLD实现电动汽车驱动系统的逻辑控制

电动汽车电机驱动系统的控制包含各种复杂的逻辑操作，这些逻辑操作一般使用单片机或数字信号处理器等通用微处理器来实现。采用复杂可编程逻辑器件（CPLD）来实现电机驱动系统控制的各种逻辑操作，具有对事件的响应速度快、多个事件能够并行处理等优点。文章介绍了电动汽车电机驱动系统常见逻辑操作的硬件描述语言（VHDL）模型以及用CPLD来实现这些逻辑操作的具体方法。

Logic Control of Electric Vehicle Drive System with CPLD

Many logic operations in electric vehicle drive system are dealt with universal microprocessor like Singlechip or Digital Signal Processor.In this article,Complex Programmable Logic Device(CPLD) is used to deal with logic operation,which has the merits such as responding events fleetly and synchronously.Some examples are also introduced in this article.
