| Abstract: | In the system of hybrid suspension with electromagnets and permanent magnets,a method of producing two complementary PWM wave with dead-time using CPLD is proposed.As CPLD doesn't have halting problem,the nonstop problem of the bidirectional chopper is prevented effectively,and the reliability of the control system is enhanced.In this foundation,the assistance functions such as decoding,displaying using CPLD are completed,and the integration rate of the system is enhanced.The detailed design of the CPLD module is given,and the synchronized movement of many function with the VHDL language is realized.The experimental result indicates the feasibility of the design. |
