摘要:
针对永磁同步电机驱动机械臂系统的无速度测量位置跟踪问题提出了自抗扰控制与哈密顿控制相结合的鲁棒控制策略。首先建立了考虑不确定性的电气子系统方程和机械子系统模型，依据独立关节控制思想将模型转化为单电机驱动单关节的端口哈密顿结构；然后，采用自抗扰控制思想简化系统中的机械方程，并设计级联扩张状态观测器对剩余总扰动观测误差进行估计，实现对期望位置的鲁棒跟踪，同时简单有效地获取到期望的q轴电流i_qi^*，最后，基于系统哈密顿结构设计互联、阻尼配置哈密顿控制器与H_∞控制器相结合的鲁棒哈密顿控制器，实现对电流的高精度鲁棒跟踪，并适当改进H_∞的引入时机改善了初始控制输入过大的问题。本文设计的控制算法无需速度测量、计算量小、稳态精度高、鲁棒性强。与其他控制方案的仿真对比结果验证了本文所提出的控制方案的有效性，级联ESO与传统ESO相比关节位置跟踪精度提升了0.003 rad，改进的鲁棒哈密顿控制器与哈密顿控制器相比关节位置跟踪精度提升了0.005 rad，电流跟踪精度显著提升，改进H_∞的引入时机初始控制输入显著降低。
Abstract:
Aiming to solve the position tracking problem of permanent magnet synchronous motor driven manipulator system,a robust control strategy combining active disturbance rejection control and Hamiltonian control was proposed.Firstly,the electrical subsystem and mechanical subsystem model considering uncertainty were established,and the model was transformed into a single-motor-driven single-joint port Hamiltonian structure according to the independent joint control idea.Then,the cascaded extended state observer was designed to estimate the total disturbance of the mechanical subsystem,and the designed control law achieved robust tracking of the desired position while simply and efficiently obtaining the desired q-axis current.Finally,a robust Hamiltonian controller which could combine the interconnections and damping assignment Hamiltonian controller with the H∞ controller based on the system Hamiltonian structure was designed to achieve high precision robust current tracking,and improves the problem of large initial control input by improving the timing of introducing H∞. Compared with modelless active disturbance rejection control of the electrically driven robot manipulators,the simulation results verified the effectiveness of the proposed control scheme.Compared with traditional ESO,the joint position tracking accuracy of the cascaded ESO could be improved by 0.003 rad.Compared with the Hamiltonian controller,the joint position tracking accuracy of the improved robust Hamiltonian controller was improved by 0.005 rad,the current tracking accuracy was significantly improved,and the initial control input of the improved H∞ introduction timing was significantly reduced.
