    • An adaptive control system for adaptively controlling a turning operation performed at a workpiece by a turning tool adjusts a controlled input operation parameter F to maintain an output operation parameter DELTA M substantially at a predetermined value DELTA Mo to compensate variation of the output operation parameter DELTA M caused by the variation of at least one operation condition B = B(t). The system comprises a sensor (8) of the output operation parameter DELTA M for providing a signal Uc proportional to a current value DELTA Mc, and an adaptive controller (10) for determining a value Fc to which the input operation parameter F should be adjusted, as a function of kUc, where k is a signal transmission coefficient which comprises an invariant signal transmission coefficient component ko inversely proportional to DELTA Mo. The adaptive controller (10) includes an amplifier (14) transforming the signal Uc into koUc, and an input parameter override unit (9) controlled to adjust the controlled operation input parameter to Fc. The adaptive controller (10) further comprises a correction processing means (16) calculating kcUc, where kc is a varying signal transmission coefficient component whose current values depend on the variation of the operation condition B = B(t). The adaptive controller (10) is capable of calculating k=f(ko,kc).
    • 用于通过转向工具自适应地控制在工件处执行的转弯操作的自适应控制系统调节受控输入操作参数F,以使输出操作参数DELTA M基本保持在预定值DELTA Mo,以补偿输出操作参数DELTA M的变化 由至少一个操作条件B = B(t)的变化引起的。 该系统包括输出操作参数DELTA M的传感器(8),用于提供与当前值DELTA Mc成比例的信号Uc;以及自适应控制器(10),用于确定输入操作参数F应被调整到的值Fc ,作为kUc的函数,其中k是包括与DELTA Mo成反比的不变信号传输系数分量ko的信号传输系数。自适应控制器(10)包括将信号Uc转换为koUc的放大器(14),以及 控制输入​​参数超控单元(9),将受控操作输入参数调整为Fc。 自适应控制器(10)还包括计算kcUc的校正处理装置(16),其中kc是其当前值取决于操作条件B = B(t)的变化的变化信号传输系数分量。 自适应控制器(10)能够计算k = f(ko,kc)。
