Description
Summary:	This paper describes the practical estimation of a linear discrete-time state-space model of the high voltage unit in an electrostatic precipitator used in a large cement factory. A computer interface system is developed to facilitate measurements of voltages and currents at both LV and HV sides of the transformer circuit of the HV unit. The unbiased recursive least-squares algorithm is used to identify the system model based on real measurements of the inputs and outputs. The input/output data is obtained by subjecting the system to a pseudo random binary sequence superimposed on its input. The identified model is assessed by comparing simulation and real system variables. Practical results of the real system are presented to show the model validity.
