A universal digital control platform for electrical machines based on the programmable logic devices and digital signal processors technology

A novel digital platform based on the programmed logic device (PLD) and digital signal processor (DSP) has been developed for motor drives. Compared with the traditional single DSP control method, the new platform has many good performances such as the flexibility, versatility and powerful computational capability which are configured by a field-programmable gate array (FPGA) and complex PLD (CPLD). All these features ensure the platform is suitable to realize complex control algorithm such as the space vector modulation technique used in the multi-level inverters and other power electronic systems.
