    • An object model generation device and method are provided to automatically generate a numerical model of an object without expert knowledge by collecting only time series data of an actual controlled variable without collecting the time series data of a manipulated variable. An object model generation device for generating an object model by searching an object model parameter value of a numerical model of an object includes an actual controlled variable memorizing unit(6) memorizing time series data of an actual controlled variable output by controlling the actual object; a model memorizing unit(1) memorizing the numerical model of the object having one or plural parameters in advance; a controller memorizing unit(2) memorizing controller algorithm for imaginarily generating a controller, in advance; a simulation computing unit(5) executing simulation for simulating the control response of a control system comprising the object displayed by the numerical model and the controller displayed by the controller algorithm; an evaluation function computing unit(7) calculating an evaluation function value indicating approximation between the actual controlled variable and a model controlled variable by comparing the actual controlled variable with the model controlled variable output by the simulation; and an object model parameter searching and computing unit(8) executing the simulation in the simulation computing unit by gradually changing the value of the object model parameter set in the numerical model and determining the value of the object model parameter keeping the evaluation function value optimal, as the model parameter searching result.
