Excitation control method for variable speed operation of marine brushless generator
In order to deal with various uncertainties effectively and improve the anti-interference ability of excitation control,a variable speed operation excitation control method for ship brushless generators is proposed.By establishing the mathematical model of the marine brushless generator,the feedback voltage of the brushless generator is determined,and the difference between the reference voltage and the feedback voltage is the input of the fuzzy immune adaptive PID control out-er ring.Through its adaptive mechanism,the parameters of the control outer ring are adjusted in real time to cope with vari-ous uncertainties,and the precise reference value of stator harmonic excitation winding current is output.Improve the anti-in-terference ability of excitation control.The difference between the current value and the reference value of the stator harmon-ic excitation winding is used as the input of the fuzzy PI control loop and the output of the excitation control signal to realize the excitation control of the marine brushless generator in variable speed operation.Experimental results show that this meth-od can effectively control the excitation of marine brushless generator in variable speed operation,ensure the generator out-put stable voltage,and make the generator speed stable near the set speed.
