This paper presents a systematic approach to design a Lyapunov based super twisting differentiator. The differentiator will be shown convergent in a finite time whilst the relevant time is accurately estimated.  This differentiator is the main part to establish the sliding surface in higher order sliding mode. The differentiator  is used in the prescribed control structure  to regulate pressure...

This article proposes a novel hybrid metaheuristic technique based on nonsingular terminal sliding mode controller, time delay estimation method, an extended grey wolf optimization algorithm and adaptive super twisting control law. The fast convergence is assured by controller owing to its inherent nonlinear property no prior knowledge of the robot dynamics required due estimation. proposed det...

This paper presents a tracking control method for pneumatic muscle actuators (PMAs). Considering that the PMA platform only feedbacks position, and velocity disturbances cannot be observed directly, we use extended-state-observer (ESO) simultaneously estimating system states by using measurable variables. Integrated with ESO, super twisting controller (STC) is design based on estimated to reali...

The induction motor (IM) drives are prone to various uncertainties, disturbances, and non-linear dynamics. A high-performance control system is essential in the outer loop guarantee accurate convergence of speed torque required value. Super-twisting sliding mode (ST-SMC) fractional-order calculus have been widely used enhance (SMC) performance for IM drives. This paper combines ST-SMC attribute...

This paper proposes a super-twisting sliding mode control for multifunctional system that includes Photovoltaic (PV) connected to the grid through Active Power Filter (APF). The latter is implemented improve power quality in side, and injecting provided photovoltaic into grid. Sliding known as powerful with good performance transient steady-state conditions. In this work, Super-Twisting Mode Co...

Subsynchronous oscillation, caused by the interaction between rotor side converter (RSC) control of doubly fed induction generator (DFIG) and series-compensated transmission line, is an alleged subsynchronous (SSCI). SSCI can cause DFIGs to go offline crowbar circuit breakdown, then deteriorate power system stability. This paper proposes a novel adaptive super-twisting sliding mode mitigation m...

This paper introduces a robust adaptive sliding mode control to solve finite-time stability of the uncertain nonlinear systems with multiple inputs and outputs (MIMO). The proposed algorithm guarantees strict robustness fast convergence system trajectories zero in finite time under negative effects uncertainties and/or external disturbances. fundamental methodology is based on an improved modif...
