Tubular permanent magnet motor (TPMM) can offer great thrust force density and high efficiency. To enhance its robustness against disturbances and solve the contradiction between response time and overshoot, a novel sliding mode control strategy based on disturbance observer (DOB-SMC) was proposed for a TPMM velocity drive system. The novelty of the proposed velocity control strategy lies in the incorporation of the mismatch disturbance observer in the sliding surface and the sliding mode control (SMC) law, and the introduction of internal model control (IMC) into the SMC law. The velocity control system is transformed to a first-order inertia model by IMC, thus the dynamic response performance is improved. The mismatched disturbances are estimated and the equivalent control voltage is employed, and then the effect of mismatched and matched disturbances can be restrained with little chattering. The simulated and experimental results are presented as validation for the proposed strategy.

通过扰动观测器对TPMM速度驱动器进行复合滑模控制

管状永磁电动机（TPMM）可提供很大的推力密度和高效率。为了提高其抗干扰的鲁棒性并解决响应时间与超调之间的矛盾，提出了一种基于干扰观测器（DOB-SMC）的新型滑模控制策略。所提出的速度控制策略的新颖之处在于将失配扰动观测器并入了滑模和滑模控制（SMC）律，并将内部模型控制（IMC）引入了SMC律。通过IMC将速度控制系统转换为一阶惯性模型，从而提高了动态响应性能。估算失配干扰并采用等效控制电压，这样就可以在几乎没有颤动的情况下抑制失配和匹配干扰的影响。仿真结果和实验结果作为对所提出策略的验证。
