Parameter Identification Via Second Order Sliding Modes

A method for identification of any even number of parameters of the process transfer function from the test on the process, which involves application of the modified twisting algorithm, is proposed. Equations for determining the unknown parameters can be written separately for the magnitude and the argument of the transfer function that simplifies the task of identification. As a result, the problem can be reduced to the iterative solution of a system algebraic equations. Examples are provided
