Abstract
A control apparatus for controlling an object that is modeled using at least one model parameter is provided. The control apparatus comprises an identifier, a controller and a modulator. The identifier identifies the model parameter. The controller is coupled to the identifier and uses the model parameter to determine a reference input so that an output of the object converges to a desired value. The modulator is coupled to the controller and applies any one of a delta-sigma modulation algorithm, a sigma-delta modulation algorithm and a delta modulation algorithm to the reference input to determine an input into the object. The model parameter is identified based on the output of the object and the reference input. Since the identifier determines the model parameter based on the reference input, the model parameters is prevented from vibrating.
