混合输入机构实现给定轨迹的模糊控制（Hybrid Machine for Implementing Given Trajectory by Fuzzy Controller）
混合输入机构 模糊控制器 速度波动
2009/5/22
混合输入机构运转过程中，由于惯性力等因素的存在，恒速电动机会产生一定的速度波动，影响了输出运动轨迹的精度。针对混合输入机构中恒速电动机不可控的特点，提出了伺服电动机实时跟踪恒速电动机转速的控制策略。构建了混合输入机构控制平台，设计了伺服电动机对恒速电动机转速实时跟踪的模糊控制器，对恒速电动机的速度波动进行补偿，以保证精确实现给定轨迹。实验结果表明模糊控制器具有较高控制精度和稳定性。
