Abstract: This paper investigates the optimized tracking control problem for nonlinear single-input-single-output systems in nonstrict-feedback form. An intelligent approximation-based optimized backstepping control strategy is developed using reinforcement learning. An improved variable separation method is presented to address the algebraic loop issue arising from the implementation of virtual optimized controls. The designed actual optimized controller ensures that the system’s output converge to a small neighborhood of the reference signal and all the signals in closed-loop systems are semiglobally ultimately uniformly bounded.
