A new method is employed to identify the unknown parameters of a bilinear system. This method expands the system input and output by block pulse functions and reduces the original identification problem to an algebraic form. Furthermore, the dyad formed by block pulse functions and its integral are

## Walsh product matrix is formed by the multiplication of Wakh vector and its transpose. The operation of Walsh product matrix on a coefficient vector equals the product of a coefficient matrix and a Walsh vector. This unique property of Walsh functions is used to determine the unknown parameters o
A new technique for the identification of general biZinear systems is presented. !l%e model reference adaptive systems (MAR.9 technique together with the direct method of Liapunov are used to construct the identifier for the system parameters.

Orthogonality of Walsh functions is used to obtain independent parameter estimation equations for continuoustime dynamic systems. The conditioning of these equations is optimized by use of optimum inpqts and is based on maximizing analytic nowlinear functions of Walsh coefficients. ## It is shown
