Improvement of acceleration performance control method for ship power propulsion system
Improvements and optimizations are implemented for the acceleration performance control method of ship propulsion systems.Firstly,design an acceleration performance control model for the ship's propulsion system,which achieves acceleration performance control of the propulsion system through the combination of propulsion motor thrust control and blade pitch adjustment.After the ship control room transmits the acceleration command to the VDF central processing unit,the PLC software inside the frequency converter is pushed to obtain the control command,and the fuzzy controller is used to control the speed of the acceleration motor.To address the issue of control deviation,a genetic algorithm is used to improve the fuzzy controller,which achieves acceleration performance control by accurately controlling the thrust generated by the motor;After obtaining control information,the VDF central processing unit transmits the pitch control information to the CPP processing unit,thereby achieving control of the pitch.The experimental results show that this method can effect-ively control the acceleration performance of the research object,with a control response time of less than 1 second,and has strong anti-interference ability during the joint control mode control process
