Supported by Shanghai Municipal Science and Technology Commission: Research on heave Motion Compensation technology of Offshore mining ship, No.19DZ1207304
Mining ship is an essential Marine equipment in the exploitation of Marine resources. In order to reduce the heave motion, it is necessary to compensate the mining ship for heave compensation. A composite active and passive integrated heave compensation system based on composite hydraulic cylinder is proposed. In order to improve the control accuracy, an active compensation control strategy based on Mamdani fuzzy PID is proposed to reduce the compensation error under heave interference. Firstly, the heave compensation principle was introduced, and the calculation process of ship"s heave amplitude under different sea conditions was deduced based on Mohr"s empirical formula, then the promotion heavy compensation mathematic model and transfer function of the system were established, finally the proposed fuzzy control algorithm was used to control the system under the regular ocean wave and irregular wave and compare with the traditional PID control effect. The results show that under the two kinds of ocean wave, the error of the fuzzy control algorithm is less than the error of the traditional PID control algorithm, It can be seen that fuzzy control algorithm has obvious advantages.
