    摘要: A motor control system which uses position command values output from control parts for motors and feedback information from axes which are driven by the command values for feedback control of the axes in an environment in which when one or more axes among axes which are driven by motors are driven, the other axes receive interference, which motor control system calculates acceleration of an axis which is driven by a motor by a first control part, sends the calculated acceleration to a second control part using a communication device, multiplies the acceleration which was input at the second control part with a compensation gain to calculate a position compensating value which compensates the position of an axis, adds the calculated position compensating value to the position command value of the axis, and uses the compensated position command value to control the position of the axis.

    摘要: The drive control apparatus for a linear actuator according to the present invention uses fine actuators, such as an electrostrictive element, so that it is possible to manufacture a linear actuator drive control apparatus obtaining big driving force in spite of a size considerably smaller than the conventional magnetic motor and linear motors utilized electromagnetic force. In addition, since the fine actuator and the driving base repeats their fixings and seperatings, it is possible to make the driven stroke range of the driving base wide. Since the fixing operation and the separating operation are carried out when the speeds of the fine actuator and of the driving base are almost the same, generation of the shock due to sudden speed change of the fine actuator and the driving base at the same of their fixing and separating is prevented, and it is possible to obtain smooth driving of the driving base. Control of the speeds of the fine actuator enables to finely and precisely control the speed of the driving base.

    摘要: Embodiments of the present invention are directed to a controller that is configured to limit the rate of change of speed of a motor (e.g., the acceleration or deceleration) regardless of the operating mode of the motor (e.g., speed, torque, or power control mode). The controller can include an acceleration estimator which monitors the output speed of a motor and provides an acceleration-limited speed set point. The output of the acceleration estimator may be limited to a range of acceptable acceleration values that correspond to the required limits of acceleration and deceleration. The acceleration estimator can be configured such that it causes the speed regulator to override the torque and/or power regulators when the acceleration range is exceeded.

    摘要: An electro-hydraulic servo control system which has N dynamic state variables and includes a servo actuator adapted to variably position a load mass. An actuator control system includes sensors coupled to the actuator for providing indications of X measured state variables, such as actuator position and/or velocity, and a digital observer responsive to the X measured actuator variables for estimating the remaining N-X variables at the actuator such as velocity and/or acceleration. Signals indicative of measured and estimated state variables are fed to a comparator together with a state command signal, for obtaining a difference or error signal to provide a control input to the actuator. The observer electronics include digital computation means suitably programmed to estimate N state variables as solutions to N linear equations for N unknowns. Equation constants, which are functions of actuator and driven mass physical characteristics, are entered through operator-adjustable resistors or are down-loaded from a remote system into storage registers.

    摘要: A closed loop control system for a pneumatic actuator using position and pressure feedback signals. The feedback signals are supplied to a microprocessor which successively generates a desired acceleration, a desired actuator force, a desired gas pressure, and a gas mass flow rate command for a gas flow controlling valve. The use of the gas flow rate as a control variable decouples pneumatic ronlinearities from the control loop. Nonlinear viscous friction, coulomb friction and load effects are decoupled from the control loop prior to the calculation of the desired pressure. An improved trajectory is achieved by employing a plurality of trajectory phases, including a velocity control phase.

    摘要: A robot control apparatus includes a sine wave signal-outputting device, an operating device, a command device for outputting a current value, a substracting device, an electric power amplifying device, and a programmable filter. The outputting device outputs sine wave signals of first and second phases having a phase difference of approximate 90.degree. generated by a position shift of a movable portion of a motor for driving an arm of a robot. The operating device determines the difference between a product of a value corresponding to the first phase signal and a value obtained by first-order differentiating a value corresponding to the second phase signal and a product of a value corresponding to the second phase signal and a value obtained by first-order differentiating the value corresponding to the first phase signal. The subtracting device subtracts the current value from the value outputted from the operating device based on the current value, and outputs a signal corresponding to a result the subtraction. The amplifying device outputs a signal to supply electric power to the motor in response to the signal outputted from the subtracting device. A filter operates as one of a high-pass and a band-pass filters according to the difference outputted from the command device, and is provided between the outputting device and the operating device and operates as a high-pass filter when the arm starts moving and the band-pass filter operates when the arm stops in contact with an object, and outputs a signal to the operating device.
