    • A robust digital controller is equipped with a high degree of approximation and is able to incorporate a novel two-degree-of-freedom robust digital control system without substantially considering the magnitude of the control inputs and there is provided its designing device. A control compensating means is configured as an integral type control system in which a discrete transfer function Wry (z) between a target value r and a controlled variable y is approximated to a higher-approximate quadratic approximate model transfer function Wm (z) and an arithmetic processing can be performed within the digital controller based on the model transfer function Wm (z). Further, the designing device automatically calculates parameters constituting the control system. Consequently, a robust digital controller can be easily realized that is equipped with a high degree of approximation as compared with a conventional approximate digital control system for realizing a first-order model and is robust against output noises.
    • 强大的数字控制器具有高度的近似性,并且能够引入一种新颖的两度自由度鲁棒的数字控制系统,而基本上不考虑控制输入的大小,并提供其设计装置。 控制补偿装置被配置为整体式控制系统,其中目标值r和受控变量y之间的离散传递函数Wry(z)近似于较高近似二次近似模型传递函数Wm(z),并且 可以基于模型传递函数Wm(z)在数字控制器内执行算术处理。 此外,设计装置自动计算构成控制系统的参数。 因此,与用于实现一阶模型的常规近似数字控制系统相比,可以容易地实现具有高度近似的鲁棒数字控制器,并且对输出噪声是鲁棒的。
