Abstract: Improvement of following performance about a target value is achieved in a control system, particularly a feedback control system. A command value correcting device corrects a current-control-cycle command value received with a feedback controller using a current-control-cycle controlled variable of a control target.

Abstract: A characteristic change, disturbance, and an abnormal state are accurately detected with no use of a high-accuracy simulation model. A control device for controlling a control target includes a predictive value calculator that outputs a predictive value of an output value to an input value with respect to a model of the control target, a prediction error calculator that calculates a relational value indicating a relationship between the predictive value and a measured value of output of the control target; and a change detector that compares a first relational value to a second relational value, the first relational value being the relational value in a reference state in which the control target operates normally, the second relational value being the relational value in an operating state in which the control target is operated.

Abstract: An input/output map storage unit stores an input/output map representing connection relationships between ports of controllers and ports of input/output devices. A model program execution unit executes a model program for a controller, a model program for an input/output device and a model program for a control target apparatus that are selected from a library by a user through a user input unit. The model program execution unit, when executing the model program for the controller, performs data exchange between the model program for the controller and the program for the input/output device, based on the input/output map.

Abstract: A simulation unit receives a series of simulation command values, calculates and outputs a series of simulation values of a position or speed of an object. A control unit provides the simulation unit with the series of simulation command values and displays the series of simulation values. The control unit acquires a series of actual command values output by the control apparatus at predetermined intervals in control cycles for controlling the operation of the object and a series of actual values of the position or speed of the object, acquired by the control apparatus at the predetermined intervals. The control unit provides the simulation unit with the series of actual command values serving as the series of simulation command values. The control unit displays the series of actual values in a mode where the series of actual values can be compared with the series of simulation values.

Abstract: A simulation apparatus includes a processor that executes a simulation of a control program executed on a controller. The controller controls motion of a machine that handles an object. The processor includes: a motion control device that controls motion of a virtual machine based on a motion command to move the virtual machine in a virtual space, with the virtual machine corresponding to the machine; a determination device that determines whether a volume of a region, where a work space in which the virtual machine works overlaps with the virtual object, is equal to or greater than a predetermined reference value, the virtual object being handled by the virtual machine and corresponding to the object; and a follow-up device that makes the virtual object follow the motion of the virtual machine based on the motion command when the volume is equal to or greater than the reference value.
