摘要

通过结合浮子在波浪中的受力运动方程与永磁同步直线电机模型,构建等效电路,设计一种基于降阶线性状态观测器（RLESO）的双闭环串级线性自抗扰（LADRC）控制算法,且以永磁同步直线电机电压电流为输入,设计无传感器速度滑模观测器替代传统速度传感器。仿真结果表明,所提速度观测器可对实际速度予以准确估计,基于RLESO的串级LADRC控制策略于表现出良好的跟踪效果,拥有较好得抗干扰能力和鲁棒性,功率输出优化效果明显。

Abstract

By combining the equations of motion of the force of the float in the wave with the model of the permanent magnet synchronous linear motor, a double closed-loop linear active disturbance rejection control （LADRC） algorithm based on the reduced-order linear state observer （RLESO） is designed. Additionally, a sensorless speed sliding mode observer is designed to replace the traditional speed sensor using the voltage and current of the motor as the input. The simulation results demonstrate that the proposed speed observer can precisely estimate the actual speed, and the RLESO-based cascade LADRC control strategy demonstrates good tracking effect, anti-jamming capability and robustness. Moreover, the power output optimization effect is obvious.
