책소개

In this article, Smooth Super-twisting Sliding Mode Control (SSTWSMC) is
investigated for the class of underactuated system. In underactuated systems, the
control design is not directly applicable as for other systems (known as fully
actuated systems). Therefore, at initial step, a nonlinear uncertain model of
systems is transformed into the controllable canonical form, and then Smooth
Super Twisting (SSTW) based Sliding Mode Control (SMC) is devised for the control
design purpose for the considered class. In addition, closed loop stability of the
proposed technique is presented in a fascinating way. The effectiveness and
supremacy of the proposed control technique is proven by extensive analysis
between conventional Sliding Mode Control (SMC), Super twisting (STW) sliding
mode control and Smooth Super-twisting Sliding Mode Control (SSTWSMC). The
comprehensive analysis evaluates the attributes like robustness enhancement,
settling time, control effort, chattering reduction, overshoot, sliding mode
convergence, etc. and is supported by simulations as well as practical
implementation on ball and beam balancer (which is considered as application
example).
