“…However, many results in these papers were based on traditional backstepping technique as well as the approximation features of FlSs or NN [18,24], as we known that in the recursive process of these approximation and backstepping-based approaches, as the order increased, the design procedure can cause 'explosion of complexity' [26,28,34], many adaptive parameters were needed to be adjusted [30][31][32][33][34] even together with dynamic surface control (DSC) method [13], therefore, the online computation burden is rather heavy, especially in dealing with MIMO or non-strict feedback nonlinear systems [18,24]. Different from these results [30][31][32][33][34], or the optimal control method to compensate the dead-zone [37], in this paper, we will explore a direct novel alleviating computation NN control method for nonlinear non-strict feedback systems.…”
