    • An instruction value Duty for bringing a slip rotation speed Nslip to a target rotation speed is feedback-controlled based on a difference e between the slip rotation speed Nslip and the target rotation speed, and a weight &thgr; from a parameter map. Weights &thgr; are assigned individually to a plurality of models, each of which includes a group of parameters and which are used to form a control model that represents a slip control system. Based on a weight that is assigned to one of the plurality of models, a weight that is assigned to at least one model that is other than the one of the plurality of models is specified. Thus, the amount of calculation required can be reduced by estimating weights for the models including the groups of parameters, which contain parameters that are used to construct the control model, instead of directly estimating the control model-constructing parameters.
    • 基于滑移转速Nslip与目标转速之间的差e和来自参数图的权重θ来反馈控制用于使滑移转速Nslip达到目标转速的指令值。 权重θ被分别分配给多个模型,每个模型包括一组参数,并且用于形成表示滑移控制系统的控制模型。 基于分配给多个模型中的一个模型的权重,指定分配给除了多个模型中的一个以外的至少一个模型的权重。 因此,通过估计包括参数组的模型的权重,可以减少所需的计算量,该参数组包含用于构建控制模型的参数,而不是直接估计控制模型构建参数。

    • A control apparatus for controlling a control system having a sliding resistance by using a sliding mode control method determines a deviation of an actual value of a quantity of state that is to be caused to follow a target value from the target value (step 1), calculates a switching surface &sgr; from the deviation (step 2), and determines a corrected switching surface &sgr;′ by adding a carrier wave to the calculated switching surface &sgr; (step 3). The carrier wave is expressed by a periodic function, for example, a sine wave, a sawtooth pulse wave, or the like, and has finite gradients on its waveform. Then, the control apparatus outputs an amount of operation u based on the value of the corrected switching surface &sgr;′ (step 4). The amount of operation u behaves in a manner similar to that in an ordinary sliding mode control method when the switching surface &sgr; is not close to zero. When the switching surface &sgr; is close to zero, the amount of operation u periodically changes similarly to a dither signal. Therefore, the control apparatus is able to prevent deterioration of the controlling performance with respect to the sliding resistance and retain excellent robustness of the sliding mode control.
    • 通过使用滑动模式控制方法来控制具有滑动阻力的控制系统的控制装置根据目标值确定与目标值相关的状态量的实际值的偏差(步骤1) 根据偏差计算切换面sigma(步骤2),并通过将加载载波加到计算出的切换面sigma(步骤3)来确定校正的切换面sigma'。 载波由周期函数(例如,正弦波,锯齿波等)表示,并且在其波形上具有有限的梯度。 然后,控制装置根据校正后的切换面sigma'的值输出运算量u(步骤4)。 当切换表面sigma不接近零时,操作量u以与普通滑动模式控制方法类似的方式起作用。 当开关表面sigma接近零时,操作量u周期性地变化,类似于抖动信号。 因此,控制装置能够防止控制性能相对于滑动阻力的劣化,并且保持滑动模式控制的良好鲁棒性。
