Abstract: A control device for tuning a servo motor is suggested. The control device comprises a calculation unit configured to determine a current proportional speed gain of the servo motor and to calculate a stabilization time ratio based on a current stabilization time of the servo motor and a target stabilization time, a determination unit configured to select a gain determination process based on the calculated stabilization time ratio, to determine a next proportional speed gain using the selected gain determination process starting from the current proportional speed gain, wherein the calculation unit is further configured to update parameters of the servo motor according to the determined next proportional speed gain, and a control unit configured to generate a control signal for controlling the servo motor for driving a load based on the updated parameters.

Abstract: The invention supports the easy and appropriate setting of a plurality of control parameters. A setting support device of the invention includes: a test action instruction part, for changing at least one value among control parameters, so as to enable a servo driver to actually control test actions, or controlling test actions by utilizing the simulation of a hypothetical model; and a performance index calculation part, for working out performance indexes of the control of the servo driver according to a result of test actions.

Abstract: The present invention implements a model-tracking motor control apparatus for stabilizing behavior of a controlled object. The control apparatus (1) includes: a feedback control part (20), generating a driving torque instruction value used to enable the servo motor (2) to perform driving based on a detection value of an encoder (4) that performs detection on a rotational state of a servo motor (2); and a feedforward control part (10), generating a model torque instruction value, and outputting the model torque instruction value to the feedback control part (20), where the feedforward control part (10) has a model torque limiter (104) that limits the model torque instruction value within a first limit range.

Abstract: Control that is less likely to cause an overshoot is performed when an actual inertia value is yet to be determined. A development support apparatus sets a ratio of a position proportional gain to a velocity proportional gain to a value smaller than a ratio set when a servo driver has determined an actual inertia value of a load machine.

Abstract: A control device, by which a user causes a servo motor to perform desired operation without being conscious of a maximum torque of the servo motor while easily understanding the transmission characteristic, selects which one of sliding mode control and PID control is adopted to control a servo motor based on at least one of a position deviation and a velocity deviation.

Abstract: A user can cause a servo motor to perform desired operation without occurrence of overshoot and hunting while being unconscious of a maximum torque that can be output from the servo motor. A control device that implements model following control includes a feedforward controller that implements sliding mode control.

Abstract: A temperature control system has a plurality of heaters arranged on a control target in a plurality of rows and columns, heaters of the same row being connected to a common wiring and heaters of the same column being connected to a common wiring, wirings of the rows being connected to a side of one pole of a power source via respective elements that respond to a heater firing instruction, and wirings of the columns being connected to a side of the other pole of the power source via respective elements that respond to a heater firing instruction, and a controller that controls driving of the plurality of heaters based on an operation amount that is input for controlling a temperature of the control target.

Abstract: The number of wirings and the number of switching elements are decreased in a heater, a sensor, and the like. First to ninth heaters that heat a hot plate are connected into a matrix form between first power lines in a row direction and second power lines in a column direction. The first power lines are connected to one end of a power supply through three switching elements, respectively. The second power lines are connected to the other end of the power supply through three switching elements, respectively. On-off control is performed to the switching elements to select the heater to be driven. Therefore, the number of power lines and the number of switching elements are decreased compared with a conventional technique in which the heaters are separately wired.
