摘要： A controller capable of preventing response delay and generation of vibrations attributable thereto during position control of a movable part of a machine having low rigidity. A motor for driving a machine having low rigidity is subjected to position and velocity loop control. Compensation amount Q1 proportional to command velocity obtained by differentiating a position command and compensation amount Q2 proportional to second-order differentiated command acceleration are obtained. Compensation amounts Q1 and Q2 are added together, thus obtaining a velocity offset amount Vof corresponding to a estimated torsion amount. A differentiated value of the velocity offset amount is multiplied by coefficient β to obtain a torque offset amount Tof. The velocity offset amount Vof is added to a velocity command Vcs obtained by position loop control 1. The torque offset amount Tof is added to a torque command Tc outputted in velocity loop control 2, and the result is used as a drive command to the motor. Based on the velocity and the torque offset amount Vof and Tof, a torsion amount between motor 3 and the machine is controlled. The machine position and velocity are controlled with accuracy by regular position and velocity loop control.

摘要： In an injection molding machine whose movable part is driven by an AC servo motor, d-phase current in a direction of magnetic flux produced by a field system and q-phase current orthogonal to the d-phase current are obtained through d-q conversion on the basis of drive current of the AC servo motor and a phase of a rotor. Control of current is made in DC mode on condition that the d-phase current is set to zero, and the q-phase current is adapted for a current command. Control of current in the DC mode as described above is designed to advance the phase of the q-phase current command, which is an effective component of a current command at the time of the occurrence of magnetic saturation, thereby preventing, the influence of magnetic saturation to lessen the fall of torque.

摘要： A servomotor control method capable of preventing an overshoot in positioning a movable part of a machine in the case where the position of the movable part is controlled in a full-closed loop. When an output P1 of a first acceleration/deceleration processing section of a bell-type acceleration/deceleration process becomes "0", a coefficient k3 of incomplete integration is set to a relatively small value .alpha., and a torque limit value TL is set to a relatively small value TLL. The incomplete integration is performed with the coefficient k3 set to the small value, and a torque command TC is limited to the small value, so that an output of the servomotor is reduced and torsion of a mechanical system between the servomotor and the mechanical movable part is canceled. When both the outputs P1 and P2 of the acceleration/deceleration processing sections become "0", the coefficient k3 is set to a relatively large value .beta., and a torque limit value is made larger, to perform the incomplete integration. Then, the output torque of the servomotor is increased gradually to position the movable part at the designated position.

摘要： An electric current control method for a servomotor using DQ conversion capable of increasing an acceleration torque and stabilizing a current control for deceleration when a voltage is saturated. It is determined whether the voltage command is saturated over a maximum voltage which a power amplifier is able to output (Step T1). When the voltage command is saturated, a saturation process is performed for rewriting an integrator of a Q-phase current control loop (Step T2), it is further determined whether the servomotor is in acceleration or deceleration (Step T3) and a further saturation process is performed for rewriting an integrator of a D-phase current control loop (Step T4) only when it is determined that the servomotor is in deceleration.

摘要： Disclosed is a controller for restraining vibration of a driven element driven by a servomotor. The driven element driven by the servomotor is provided with acceleration detecting means. A correction value is obtained by multiplying a detected acceleration value detected by the acceleration detecting means by a coefficient. Correction is made by subtracting the correction value from a velocity command, and velocity feedback control is executed in a velocity control processing section to obtain a current command. Further, the servomotor is driven by current control processing, whereupon the driven element is moved. If the detected acceleration value is increased by vibration of the driven element, the velocity command is corrected to restrain the vibration, so that the vibration of the driven element can be restrained. Processing time can be shortened to restrain the vibration of the driven element by executing the correction of the velocity command based on the detected acceleration value for each velocity control period.

摘要： The first object of the present invention is to provide a PDP with improved panel brightness which is achieved by improving the efficiency in conversion from discharge energy to visible rays. The second object of the present invention is to provide a PDP with improved panel life which is achieved by improving the protecting layer protecting the dielectrics glass layer. To achieve the first object, the present invention sets the amount of xenon in the discharge gas to the range of 10% by volume to less than 100% by volume, and sets the charging pressure for the discharge gas to the range of 500 to 760 Torr which is higher than conventional charging pressures. With such construction, the panel brightness increases. Also, to achieve the second object, the present invention has, on the surface of the dielectric glass layer, a protecting layer consisting of an alkaline earth oxide with (100)-face or (110)-face orientation. The protecting layer, which may be formed by using thermal Chemical Vapor Deposition (CVD) method, plasma enhanced CVD method, or a vapor deposition method with irradiation of ion or electron beam, will have a high sputtering resistance and effectively protect the dielectrics glass layer. Such a protecting layer contributes to the improvement of the panel life.
