    • A control system makes the state variable of a controlled object track that of a reference model. A disturbance observer estimates disturbance added to the control input, and the internal state variable of the object at a predetermined sampling cycle, based on the control input and observed output of the object. The observer outputs the estimated disturbance and internal state variable as disturbance and state variable estimates. A reference model tracking controller generates a control input of the object at the next sampling cycle, based on a linear control input, disturbance estimate and nonlinear control input. The linear control input is generated by a linear controller to converge an error in the state variable estimate and observed output of the object with respect to the reference state variable. The nonlinear control input is an error in the disturbance estimate with respect to disturbance actually added to the control input.
    • 控制系统使受控对象的状态变量跟踪参考模型。 扰动观察者基于控制输入和对象的观察输出来估计加到控制输入端的干扰以及预定采样周期的对象的内部状态变量。 观测者输出估计的干扰和内部状态变量作为干扰和状态变量估计。 参考模型跟踪控制器基于线性控制输入,干扰估计和非线性控制输入,在下一个采样周期产生对象的控制输入。 线性控制输入由线性控制器产生,以便相对于参考状态变量收敛状态变量估计中的误差和对象的观察输出。 非线性控制输入是相对于实际添加到控制输入的干扰的干扰估计中的误差。

    • In a magnetic disk apparatus such as a Winchester drive, a head position control mechanism is provided for locking the transducer head on a noneffective surface region of the magnetic disk, where no data is to be stored, as when the apparatus is powered off. A locking lever pivots in a plane parallel to the disk plane for movement into and out of locking engagement with a rotary member rotatable jointly with the head arm about a common axis. A solenoid holds the locking lever out of locking engagement with the rotary member during the progress of data transfer between disk and head. Upon completion of the data transfer, or when the apparatus is electrically turned off, the solenoid becomes deenergized, permitting the locking lever to be sprung into locking engagement with the rotary member. Then the head arm transports the head to, and allows the same to land on, the noneffective surface region of the disk. The head is locked in that position as long as the locking lever remains in locking engagement with the rotary member.
    • 在诸如温彻斯特驱动器的磁盘装置中,提供了一种头位置控制机构,用于将换能器头部锁定在磁盘的无效表面区域上,其中不存储数据,如同设备断电时一样。 锁定杆在与盘平面平行的平面中枢转,用于与与头臂围绕公共轴线共同旋转的旋转构件移动进入和离开锁定接合。 在盘和头之间的数据传送过程中,螺线管将锁定杆保持与旋转构件的锁定接合。 在完成数据传送时,或者当设备电气关闭时,螺线管变为断电状态,允许锁定杆与旋转构件锁定接合。 然后,头臂将磁头传送到磁盘的无效表面区域,并允许其同时到达。 只要锁定杆保持与旋转构件锁定接合,头部被锁定在该位置。

    • A gear transmission mechanism includes main transmission gearing and auxiliary transmission gearing. Main transmission gearing transmits the movement of a shift lever in a shift direction through a shift mechanism and a fork head to a sleeve, and auxiliary transmission gearing can select a high or low speed ratio in response to transmission of the movement of the shift lever to another sleeve when the shift lever is shifted from a neutral position in one shift direction or the other. The shift mechanism comprises an input member, a reversing mechanism, a reversing member, and a pair of shift heads, the input member coacting with the shift lever such that the movement of the shift lever in the shift direction results in the movement of the input member in a shift direction. The reversing mechanism is interposed between the input member and the reversing member for reversing the movement of the input member in the shift direction into movement in an opposite shift direction and for transmitting the reversed movement to the reversing member.
    • 齿轮传动机构包括主传动齿轮传动装置和辅助传动装置。 主变速传动装置将变速杆在变速方向上的移动通过变速机构和叉头传递到套筒,辅助传动齿轮传动装置可以响应于变速杆的运动传递而选择高速或低速比 当换档杆在一个换档方向上从中立位置移动时,另一个套筒。 换档机构包括输入构件,反转机构,反转构件和一对换档头,输入构件与变速杆共同作用,使得变速杆在换档方向上的移动导致输入的运动 成员在转移方向。 反转机构插入在输入构件和反转构件之间,用于将输入构件在换档方向上的运动反转成相反移动方向的运动,并将反向运动传递到换向构件。
