SDRE (Discrete-Time State Dependent Riccati Equation) technique for a class of nonlinear
discrete-time control systems which can be transformed to quasi-linear form by the formal
extraction of a small parameter. The scheme for the proof of the stability of the closed-loop
system has been included, it is carried out along the line of the Lyapunov formalism. The
proposed regulator design algorithm significantly reduces computational costs and helps to …
