摘　　要：针对船舶智能操控仿真平台SIHC(ship intellzgent handle and control)集成的模糊自整定PID(proportion integral derivative)航向控制算法对不同船型存在适应性问题,分析其原因并加以改进。对于不同船型,运用K、T简易计算方法获得高精度的K、T值,同时制定不同系统阻尼系数ξ取值优化策略,改进PID初始值,实现对模糊自整定PID航向控制算法的优化。Matlab仿真测试结果表明,改进的模糊自整定PID航向控制算法提高了对不同船型的适应性。For the adaptation problems for different types of ships when using SIHC simulation platform integrated fuzzy self-tuning PID control algorithm, the reasons are analyzed with improvements made. For dif-ferent ship types, different damping factor value optimization strategies are designed to improve the initial val-ue of PID, so as to achieve the optimization of fuzzy self-tuning PID control algorithm. The test results from the simulation of Matlab show that the improved fuzzy self-tuning PID control algorithm effectively improves the course automatic control performance of different kinds of ships.
