The structure selection of linear switched reluctance generator is carried out.Based on the structural characteristics and operating principle of a double sided linear switched reluctance generator,a wave energy generation system with a double sided linear switched reluctance generator as a wave energy conversion device was established.The excitation power,power generation,and voltage output waveforms for the fixed on/off position control methods were analyzed.The power analysis of the double sided linear switched reluctance power generation system was performed.The results show that the double sided linear switched reluctance power generation system has continuous generation capability,and the output efficiency is up to 80.6%.The double closed-loop control strategy of voltage PID control outer loop and position inner loop control was used to simulate the double sided linear switched reluctance generator system.The system simulation results showed that the double closed-loop control strategy achieved constant pressure,thus verified the feasibility of the double closed-loop constant voltage control strategy in the double sided linear switched reluctance power generation system.
