Abstract This paper focuses on the problem of rapid tracking engine transient pressure, an improved super twisting algorithm (STA) is adopted to control intake pressure engine. The high altitude platform analyzed systematically, mathematical model derived, and system object are established. It basis classical STA method has better effect than PID methods LADRC. Transient state tests under three...

In this paper, a wind power system based on a doubly-fed induction generator (DFIG) is modeled and simulated. To guarantee high-performance control of the powers injected into the grid by the wind turbine, five intelligent super-twisting sliding mode controllers (STSMC) are used to eliminate the active power and current ripples of the DFIG. The STSMC controller is a high-order sliding mode cont...

This work addresses the modelling and control aspects for quadcopter or drone unmanned aerial vehicles (UAVs). First, the mathematical model of the drone is derived by identifying significant parameters and the negligible ones are treated as disturbances. The control design begins with the switching surface selection, then, an Adaptive Super Twisting Sliding Mode (ASTSM) Control algorithm is ap...

This paper presents a new shared lateral control approach to deal with the transition management between human driver and autonomous system. The objective of this is realize smooth safe switching two agents steering inputs during lane keeping maneuver. different driving modes including system are detailed. Two defined. acts on vehicle's control. consists longitudinal controller developed based ...

In this paper, an angular tracking control based on adaptive super twisting algorithm (ASTA) for a Twin Rotor System is presented. With the aim of implementing the ASTA control and taking into consideration the difficulties of measuring some of its states, a Nonlinear Extended State Observer (NESO) is employed to estimate the vector state and furthermore unmeasured dynamics. This scheme increas...

A robust consensus controller is proposed for heterogeneous higher order nonlinear multi-agent systems (MAS), when the agent dynamics are involved with mismatched uncertainties. A distributed consensus protocol based on a time varying nonhomogeneous finite time disturbance observer (FTDO) and sliding mode control is designed to realize the network consensus of higher order MAS. The time varying...

We present an algebraic approach to string theory. An embedding of sl(2|1) in a super Lie algebra together with a grading on the Lie algebra determines a nilpotent subalgebra of the super Lie algebra. Chirally gauging this subalgebra in the corresponding Wess-Zumino-Witten model, breaks the affine symmetry of the Wess-Zumino-Witten model to some extension of the N = 2 superconformal algebra. Th...

In order to deal with the boost converter non minimum phase property and to solve the Sliding Mode Control (SMC) major problem (the chattering phenomenon), a new backstepping Sliding Mode Controller is developed. In this paper, a comparative study between the proposed controller and the (2-SMC)super twisting and the classical SMC is provided in order to evaluate each controller. Simulations and...

We present a definition of a (super)-modular functor which includes certain interesting cases that previous definitions do not allow. We also introduce a notion of topological twisting of a modular functor, and construct formally a realization by a 2dimensional topological field theory valued in twisted K-modules. We discuss, among other things, the N = 1-supersymmetric minimal models from the ...
