| 中文摘要 |
| 对船舶舵机使用的电液负载模拟器, 建立了传递函数模型, 给出了频率特性. 根据这个模拟器的实时性和跟踪精度指标, 设计了主从式结构计算机控制系统; 其中采用了自适应模糊PID控制器, 以保证系统的鲁棒性能; 又设计了前馈控制器, 提供速度补偿和加速度补偿, 使系统有多余力时, 能够满足性能指标. 实际加载实验表明, 无论主动或被动加载, 其精度都满足设计指标, 并且系统工作稳定可靠. |
| 英文摘要 |
| For the electro-hydraulic load-simulator employed by the marine rudder, we establish its transfer function model and present its frequency characteristic. Based on the real-time operation requirements and the target-tracking accuracy, we design a master-slave computer control system. In this control system, a fuzzy adaptive PID controller is employed for ensuring the robust performance. A feedforward compensator with speed and acceleration compensations is also designed for ensuring the performance requirements when there are superfluous forces. Practical load-experiment results show that this system can work steadily and reliably, and the accuracies of active and passive loads also satisfy design requirements. |
