“…The first order (conventional) SMC as in (17) is discontinuous in nature. Practically such discontinuous control cannot be applied at infinite frequency, this leads to the chattering that may excite unmodelled dynamics and as a result system may under perform or may result into the actuator failure.…”

“…Follow from (17), we can design the sliding mode control for the system (25)-(26) that initiates the sliding motion in finite time, u(t) = −B −1 2 (c 1 [A 11 e 1 (t) + A 12 e 2 (t)] +A 21 e 1 (t) + A 22 e 2 (t) + Qsgn(s)…”

“…In [16], SMC has been employed to provide high performance over a wide bandwidth in tracking of piezoelectric driven devices. Recently, experimental results on sliding mode control of maglev system has been discussed in [17]. The conventional (first order) sliding mode control exhibits chattering phenomenon due to it's discontinuous nature, which often is not suitable for practical applications.…”

This article presents the implementation results of second order sliding mode control (SOSM) for magnetic levitation system. In practical systems, especially when the actuators are electro-mechanical, the conventional (first order) sliding mode control can not be used effectively as it exhibits chattering, which is highly undesirable. Therefore, for such systems, sliding mode control of higher order can be a suitable choice as the reduce the chattering significantly. In this article the super-twisting control, which isa second order sliding mode control, is designed and implemented for the experimental setup of Maglev system, Model 730 developed by ECP systems.

“…In [5], a position tracking control is given by using sliding model control and grey system theorem. In the presence of friction to the motion of MLS, [9] investigates the position tracking problem by sliding model control method. A composite non‐linear feedback controller is presented for MLS [10] such that the closed‐loop systems exhibit the high speed response without overshoot.…”
