摘要:
A low cost control apparatus of a contact mechanism resolving a disadvantage caused when a contact body is moved to make contact with a contacted body by an actuator. A synchronizing mechanism, which a coupling sleeve rotatably and integrally provided with an input shaft is pushed against a synchronizer ring disposed between the coupling sleeve and a synchronized gear, thereby synchronizing rotational speeds of both the components to engage them, is modeled as a collision between an inertia system object and an elastic system object. A computation coefficient (VPOLE, f in Fig. 9) of a switching function for sliding mode control having a deviation between an actual position of the coupling sleeve (Psc, d in Fig. 9) and a target position (Psc_cmd, e in Fig. 9) as a state variable is changed depending on the actual position (Psc), and thereby changing a control ability of the model against a disturbance.
摘要:
A system for controlling an industrial robot, which is simplified in operation and capable of direct-teaching safely all the time. The system is provided with means (131 and 132) for monitoring a magnitude of an external force applied to the forward end of a hand during direct teaching, so that the motion of the robot can be forcibly restricted when the external force reaches a predetermined value of thereabove. Furthermore, when the system is operated to be set in a direct teach mode, a process (136) of correcting the offset of a force sensor is performed automatically. By monitoring a force detected by the force sensor, the discrimination is made as to whether an external force to operate the robot at an abnormal speed is applied to the robot or not, and, when the external force becomes higher than a reference value, a mode of prohibiting the operation of the robot by the external force (position control mode) is set, or current supplied to a servo motor is cut off to prevent the robot from going into the erroneous operation due to an erroneous control.

An actuator control apparatus (1) is provided, capable of causing a state value which changes according to the action of an actuator (10) to match a prescribed target value. A synchronizing mechanism (2) is modeled as the collision of an inertial system object and an elastic system object, and taking as a state amount the deviation between the actual position (Psc) of a coupling sleeve (6) and the target position (Psc_cmd), a computation coefficient (VPOLE) of a switching function used in sliding mode control which takes the state amount as a variable is, in a first process until the coupling sleeve (6) makes contact with a synchronizer ring, set according to the actual position (Psc) of the coupling sleeve (6), and in a process until the coupling sleeve (6) engages a synchronized gear (7), is set such that the pressing force of the coupling sleeve (6) matches a target pressing force.

A grinder robot having a grinder can be operated by both of a force control and a position control to grind a work surface quickly and accurately. When a grinding point by said grinder has not reached yet to a target position to finish grindings, force loop drive control means (C5) are selected to drive the grinder in order to grind a work by a force control. After a grinding point by said grinder has reached to said target position, then, position drive control means (C4) are selected to drive the grinder by a position control in order to execute precise grindings. A grinding amount in every grinding in a force control area is relatively large and a grinding speed in every grinding in a position control area is relatively fast. As a result, a work can be grinded quickly and accurately by the grinder robot.
摘要:
In a die casting machine that includes a shot cylinder having a ram for injecting metal into a die cavity, an electrohydraulic system for controlling operation of the shot cylinder includes an actuator coupled to the shot cylinder ram. A valve supplies hydraulic fluid to the actuator cylinder as a function of valve control signals. Microprocessor-based digital control electronics includes memory for storing a desired ram velocity profile as an incremental function of ram position. The control circuitry is responsive to signals from a sensor coupled to the actuator, indicative of position at the ram, for retrieving corresponding velocity signals from memory and supplying control signals to the valve as a function of such profile velocity signals. The control circuitry further includes facility for adjusting impact of the shot cylinder ram at the end of a cavity-filling stroke as a function of ram and actuator position and/or pressure, independently of the velocity/position profile, to reduce separation and flashing at the die cavity, and to reduce impact wear and fatigue on the overall die casting machine. A keyboard and associated operator display provide operator programmability and selection from a plurality of velocity/position profiles. The actuator and cylinder ram may be advanced in a manual mode of operation for adjustment and calibration proposes. A display associated with the keyboard graphically illustrates desired and actual velocity/position profiles during operation, together with a profile of actuator drive pressure verses position.
