    摘要: A method of controlling a DC servomotor for driving a driven member coupled by a wire to an operation member of a valve, wherein, at the start of a control, the motor is driven first to rotate the operation shaft of the valve to a limit position after the motor stops, a driving current of the motor is gradually reduced to return slowly the driven member by a tension of the wire, and a position of the driven member when the driving current of the motor becomes zero is stored as a final stop position, thereafter, a rotational range of the driven member is limited to the range between these final stop positions when the position of the driven member is controlled to coincide with a target position.

    摘要: The invention concerns a control system for a d.c. motor (10), powered by an actuating system (14) comprising: a position detector (30, 32) co-operating with the motor's rotor; a power supply circuit (34) to apply to the terminals of the motor coils a supply voltage to generate the electric current, and a control circuit (36). This system is designed to actuate the motor to move a moving part (24), with a view to reaching a target position Pc defined by a number of steps dc to be executed. During a so-called positioning phase, the control circuit (36), after observing that target position Pc has been reached, interrupts the current powering the coils and applies to them a braking pulse (If) of reverse polarity, then short-circuits them until stoppage observed by the detector (30, 32).

    摘要: The invention reduces the oscillation of the rotation speed regulator when stationarynulldespite low position resolution and a high minimum rotation speed resulting from thisnullby switching the closed-loop control structure, when the drive is moved into the nominal position, in which case the closed-loop control structure does not need to include a current regulator when stationary. The control voltage is predetermined directly by the rotation speed regulator (2null), which is in the form of a pure P-regulator. If the rotor is deflected, then dynamic negative feedback is carried out by differentiation (9) of the position (null). The position control loop (1null), which is at a higher level than the rotation speed control loop (2null), is in the form of a PI regulator in order that no permanent position errors can occur. The switching of the closed-loop control structure according to the invention is achieved by producing characteristics which are optimized as a function of the state, namely high dynamics during movement and a good unmoving position when stationary.

    摘要: Provided is a technique to suppress hunting in a range of a minimum resolution of a pulse encoder when a servo motor has reached a target position and stopped, thereby maintaining a stable stop state. A servo motor position control device uses a cascade configuration having a position control loop as a main loop and a velocity and current control loop as a minor loop. A proportion control is performed for a position control while a proportion integration control is performed for a velocity control and a current control. When the servo motor position has reached the target position and stopped (S201), a current instruction value for the current control is maintained at a value upon stop (S202) and the current control is switched to the proportion control (S204).
