摘要: 该文针对自行研制的由Mcs-96系列单片机与PWM驱动器组成的高速、高精度数字 伺服系统,提出了"模糊粗、精调整控制"和"e、é非线性量化法",并明确指出模糊控制规则状 态表中各量的物理意义,从而可有目的地对该表进行人为修正.采用上述方法后,实验表明系 统具有很高的跟踪精度与平稳性.在单元阶跃作用下,系统具有快速过渡过程和超调量近于 零的优良品质.Abstract: This paper describes a high-speed, high-accuracy digital servo-system composed of self-developed MCS-96 Series Single chip computer and PWM driver. The author suggested several methods, such as "Fuzzy rough or accurate regulating Control", "e and é nonlinear quantizing method", and explained the physical meaning of every constant in the state table. Using these methods, experiments show that the system has very high tracking accuracy and good stationary character. Under step-input, the system has a fast transient process and a very small overshoot.
