摘　　要：为了满足不同负载工况时,船用齿轮式液压舵机的舵角跟踪水平,设计船用齿轮式液压舵机负载自适应控制系统。利用数据采集模块的电流传感器、转速传感器和位置传感器,采集船用齿轮式液压舵机的电流、转速和位置数据。系统的控制模块选取TMS320F28377芯片作为控制芯片,利用舵机数据采集结果,采用三闭环控制结构,运行模糊PID自适应控制算法输出舵机参数控制量。设置舵机参数控制量作为驱动模块的输入,驱动模块利用驱动电路驱动传动机构;设置传动机构作为驱动摇臂的执行部件,实现液压舵机的控制。系统测试结果表明,所设计系统可以依据负载变化,控制船用齿轮式液压舵机舵角,精准跟踪负载正弦信号。In order to satisfy the rudder angle tracking level of marine gear hydraulic steering gear under different load conditions,the load adaptive control system of Marine gear hydraulic steering gear is designed.Using the current sensor,speed sensor and position sensor of data acquisition module,the current,speed sensor and position data of Marine gear hydraulic steering gear are collected.The control module of the system selects TMS320F28377 chip as the control chip,uses the data acquisition results of the steering gear,adopts the three-closed-loop control structure,runs the fuzzy PID adaptive control algorithm to output the steering gear parameter control.The steering gear parameter control is set as the input of the drive module,the drive module uses the drive circuit to drive the transmission mechanism,and the transmission mechanism is set as the executive part of the drive rocker arm to realize the control of the hydraulic steering gear.System test results show that the designed system can control the rudder angle of marine gear hydraulic steering gear according to load changes,and accurately track the load sine signal.
