Sliding mode control algorithms with classical and modified discontinuous reaching laws for purely magnetic attitude control of small satellites are proposed and compared with each other in this work. They are designed by following the steps characteristic to the variable structure control method and the magnetic attitude control problem. The asymptotical stability of the control laws is proven...

The equivalent force control method uses feedback control to replace a mathematical iteration required to solve the nonlinear equation of real-time hybrid test with an implicit integration method. The commonly used PID controller as a candidate of equivalent force control has only limited robustness for nonlinear systems. For the nonlinear specimen in a real-time hybrid test, the sliding mode c...

In this paper, we present a new sliding mode controller for a class of unknown nonlinear discrete-time systems. We make the following two modifications: 1) The neural identifier which is used to estimate the unknown nonlinear system, applies new learning algorithms. The stability and non-zero properties are proved by dead-zone and projection technique. 2) We propose a new sliding surface and gi...

In this paper, a global finite-time cooperative control is first time proposed for multiple manipulators. The scheme developed based on an integration between disturbance observer (FTDO) and integral sliding mode controller (FTISMC) to get high robustness against the effects of model uncertainties disturbances in system. switching term reconstructed such that desired manifold can be convergent ...

controller design remains an elusive and challenging problem foruncertain nonlinear dynamics. interval type-2 fuzzy logic systems (it2fls) incomparison with type-1 fuzzy logic systems claim to effectively handle systemuncertainties especially in the presence of disturbances and noises, but lack aformal mechanism to guarantee performance. in contrast, adaptive sliding modecontrol (asmc) provides...

─ This paper provides new analytic tools for a rigorous control formulation and stability analysis of sliding modemultimodel controller (SM-MMC). In this way to minimise the chattering effect we will adopt as a starting point the multimodel approach to change the commutation of the sliding mode control (SMC) into fusion using a first order then a high order sliding mode control with single slid...

the aim of this paper is to design a fractional order sliding mode controllers (fosmc)for a class of dc-dc converters such as boost and buck converters. firstly, the control lawis designed with respect to the properties of fractional calculus, the design yields an equiv-alent control term with an addition of discontinuous (attractive) control law. secondly, themathematical proof of the stabilit...

Abstract: The problem of static output feedback sliding mode control for a class of nonlinear delay systems with norm-bounded uncertainties is considered in this paper. Based on Linear matrix inequality approach, a new approach is given to design the static output feedback sliding mode surface. Then, a sliding mode controller is obtained which make the systems states reach the sliding mode surf...
