两个用FPGA实现的三相电机控制的例子，很有参考价值，
FPGA控制逻辑
This reference design demonstrates a logic-based, variable speed, three phase AC induction motor controller as shown in Figure 1. In this instance, logic based refers to the fact that although micro-controllers are commonly used in most induction motor controllers, this system does not utilize a micro-controller. Using sine lookup tables and Pulse Width Modulators (PWMs) programmed into the FPGA logic, it is possible to generate the signals required to drive a three phase half H-Bridge power stage (or inverter) of the type commonly used in AC induction motor drives. Because of the flexibility of the FPGA as a motor controller platform, additional functionality such as fault detection and user interface controls can be incorporated into the FPGA minimizing the requirement for additional external components.
