A workpiece simulation part estimates the amount of movement of the workpiece from drive information and estimates the current position of the workpiece by adding the amount of movement to the previous position of the workpiece, the drive information being generated for, among at least one actuator, an actuator that is assumed to constrain the workpiece under the constraint conditions. A sensor simulation part uses the current position of the workpiece to generate sensor simulation information. An input/output switching part transmits the drive information to the workpiece simulation part and transmits the sensor simulation information as alternate information of the sensor information to the control-program execution part.

Controller and conveyance system

A technique for enabling reduction in user operations. A program generating apparatus includes a control distribution unit and a communication function adding unit. The control distribution unit allocates respective control blocks of a control model to controllers, based on the control model received by a control model input unit, and setting information and connection information received by a setting information input unit. The communication function adding unit adds, when first and second ones of the control blocks are connected to each other, a communication control block to a connected part between the first and second control blocks, the first and second control blocks being allocated to different ones of the controllers in the allocated control model.

Apparatus and method for generating program

When change amount information calculated by a change amount information calculating unit satisfies a start condition and a signal condition is true for an operation instruction the start condition and the signal condition of which are defined, an operation instruction execution control unit determines a start of the corresponding operation instruction and determines operation completion based on a completion condition determined in advance of the operation instruction. An operation instruction executing unit executes the operation instruction the start of which is determined by the operation instruction execution control unit and stops the operation instruction when the operation completion is determined by the operation instruction execution control unit.

Synchronous control device

A technique that allows determination of appropriate control parameter values automatically. A constraint evaluation indicator setting unit sets, to each of a plurality of additional constraints, a third evaluation indicator obtained by combining a first evaluation indicator that indicates a level of influence on other control parameters when a control parameter is changed, and a second evaluation indicator that indicates weight according to a property including importance and the like. A constraint satisfaction solution retrieve unit retrieves a combination of control parameter values that satisfies constraints. When the constraint satisfaction solution retrieve unit fails to retrieve the combination of control parameter values, a constraint relaxing unit relaxes the additional constraints in accordance with the third evaluation indicator.

Parameter setting device

The disclosed power amplifier has: a first amplifying unit and a second amplifying unit provided with a plurality of amplifying circuits connected in parallel in which a bias voltage can be adjusted in accordance with a control signal supplied from outside, the first amplifying unit and the second amplifying unit for amplifying an input signal by each amplifying circuit and combining and outputting the amplified signal; a divider for dividing the input signal to the first amplifying unit and the second amplifying unit; and a combiner for combining and outputting an output signal of the first amplifying unit and an output signal of the second amplifying unit.
