    • There is provided a control method for sufficiently compensating the non-linear characteristic for a plant having a strong non-linear characteristic and satisfying the follow-up and stability for a plant having a large control amount fluctuation. There is provided a plant control device using modulation algorithm. The control device includes: means for calculating a temporary control input for controlling the plant output to a target value; means for dividing the temporary control input into a plurality of components; means for modulating at least one of the components; and means for adding the modulated component to another component so as to generate a control input. Thus, it is possible to minimize the input fluctuation caused by modulation while maintaining the compensation ability of the non-linear characteristic such as plant friction and hysteresis attributed to the conventional modulation algorithm. Accordingly, even in a plant in which the temporary control input is greatly changed, it is possible to prevent oscillation of the output, thereby improving the controllability.
    • 提供了一种用于充分补偿具有强非线性特性的设备的非线性特性并满足具有较大控制量波动的设备的后续和稳定性的控制方法。 提供了使用调制算法的工厂控制装置。 控制装置包括:用于计算用于将工厂输出控制为目标值的临时控制输入的装置; 用于将临时控制输入划分成多个部件的装置; 用于调节至少一个组分的装置; 以及用于将调制分量添加到另一分量以产生控制输入的装置。 因此,可以将由调制引起的输入波动最小化,同时保持归因于常规调制算法的非线性特性如工厂摩擦和滞后的补偿能力。 因此,即使在临时控制输入大大变化的设备中,也可以防止输出的振荡,从而提高控制性。
