“…Nonlinear characteristics appear in many engineering problems and real applications (e.g., [4,12,). Among the existing nonlinear control methods, Sliding Mode Control (SMC) was studied and applied due to its remarkable advantages, including rapid response, and robustness to model uncertainties and/or disturbances (e.g., [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]). Terminal Sliding Mode Control (TSMC) was first proposed by Zak [20] to improve the SMC, and then was later studied by many other researchers (e.g., [12, 13, 20, 23-27, 29-34, 36]).…”
