摘要
研究了一种新型的作动器,其特点是激振频率及振幅可在线跟踪调节,控制系统可自动识别相角差及振动幅值并自动进行调节.模糊控制器可显著地减小船舶的振动,作动器与激振器相角差控制方面首次提出了优化模糊控制算法,与传统模糊控制算法比较,模糊控制规则可根据实际测试结果进行确定,然后由程序进行分段线性优化,提高了相位角差调整的精度,理论分析和仿真结果表明,当系统模型参数发生变化时,该作动器具有良好的特性,对于抵消来自振源的振动具有很好的效果.
A new type of actuator based on fuzzy control was developed and studied in which vibration frequency and amplitude can be adjusted on-line. The control system could identify phase difference and vibration amplitude and make automatic adjustments. The fuzzy controller also demonstrated a remarkable ability to reduce vibration amplitude. Theoretical analysis and simulation results show that the actuator has good performance and effects on controlling vibrations that come from vibration headstream when model parameters changed.
