抑制管片拼装机起步冲击的模糊控制算法研究
Study on Fuzzy Control Algorithm for Restraining Starting Impact of Segment Erector

管片拼装机自身刚度以及管片转动惯量大，导致拼装机回转时存在着起步冲击现象，难以实现精准控制。针对这一问题，基于回转系统速度控制方案，提出了实现该方案的模糊控制算法；通过联合仿真技术模拟拼装机的起步工况，研究了模糊控制算法对系统动态响应的补偿作用。将所提出的模糊控制算法写入系统电子控制单元（ECU），并在合作单位进行了实车试验。模拟仿真和试验结果表明：采用模糊控制算法后，可有效改善拼装机的动态性能，能很好地抑制其起步冲击现象。
Segment erector often exists starting impact phenomenon during its rotation due to its high stiffness and the large rotational inertia of segment, which leads to the difficulty of precise control in erector system. Aiming at this problem, a fuzzy control algorithm was proposed based on the speed control method of rotating system in this paper. By using joint simulation technology to simulate the starting condition of segment erector, the fuzzy control algorithm for the compensation of the system dynamic responses was studied. The proposed fuzzy control algorithm was written into the system electronic control unit (ECU), and real vehicle test was carried on in the co-operative corporation. The simulation and test results show that the fuzzy control algorithm can effectively improve the dynamic performances of the erector and can well restrain the starting impact phenomenon
