Heel will give the ship's maneuverability , safety and economy has brought great harm to install an efficient anti- heeling device for those special ship , fiery wheels ferry , heavy-duty crane ship , a large container ship is very necessary. Traditional anti- heeling devices , such as valves switch type and pump -driven pump displacement and pump start with the change to the time limit , the response is slow , heeling compensation is low , it is difficult to meet the special needs of the ships due to . Pneumatic Anti-heeling device the advantages of rapidity , efficiency and reliability , and to promptly correct the heeling of the ship , the ship quickly reach the upright state . Currently, there is no self- production pneumatic anti - heeling device capacity , little research in this area , only the pneumatic anti horizontal tilting device works have done some research , but its core control system control strategies and implementation methods are also poorly understood. This situation, the pneumatic anti - heeling device control strategy carried out in-depth research , mainly to complete the following work : First, the analysis of the ship pneumatic anti - heeling the basic structure and working principle of the device , from the statics and the ship heeling movement dynamics two established a mathematical model of the system \anti-heeling the installation of automatic control system , using MATLAB software PID control, pure fuzzy control and fuzzy PID control system simulation , in-depth analysis of the control performance of the system , the results show that the fuzzy PID controller can well meet the pneumatic anti- heeling installation of automatic control system performance requirements ; Finally, on the the fuzzy microcontroller and digital microcontroller programming , fuzzy PID control in pneumatic anti - heeling the application of the device automatic control system .
