Disturbance-Observer-Based Terminal Sliding Mode Control for Linear Traction System with Prescribed Performance

In this article, a terminal sliding mode control (SMC) strategy based on the nonlinear disturbance observer (NDO) and prescribed performance method is proposed to deal with the speed tracking problem for permanent-magnet linear synchronous traction systems in urban rail transit. First, to improve the dynamic and static performances, a prescribed performance control characterizing the tracking perf...
