Direct power control of DFIG wind turbine systems based on an intelligent proportional-integral sliding mode control.
TLDR
The obtained results demonstrate that the proposed iPISMC method outperforms the classical PI and intelligent proportional-integral control (iPI) in terms of both active power and response time. Expand
Model-free based neural network control with time-delay estimation for lower extremity exoskeleton
TLDR
A model-free based neural network control with time-delay estimation (TDE-MFNNC) for lower extremity exoskeleton is presented and validated as more stable and effective than the traditional controllers. Expand
Algebraic switching time identification for a class of linear hybrid systems
In this paper, a method for the finite time estimation of the switching times in linear switched systems is proposed. The approach is based on algebraic tools and distribution theory. Switching timeExpand
Model free control based nonlinear integral-backstepping control for blood glucose regulation
In this paper, a Model Free Control based Nonlinear Integral Backstepping Control (MFC-NIB) strategy is developed and applied to blood glucose regulation systems, which is a typical biological systemExpand
Model-free–based terminal SMC of quadrotor attitude and position
TLDR
A model-free–based terminal sliding-mode control strategy to control the attitude and position of a quadrotor whose model includes parameter variations, uncertainties, and external disturbances is developed. Expand
Model-free based adaptive nonsingular fast terminal sliding mode control with time-delay estimation for a 12 DOF multi-functional lower limb exoskeleton
TLDR
The proposed model-free based adaptive nonsingular fast terminal sliding mode control which comprises three parts: the intelligent PI controller, time-delay estimation, and adaptive sliding mode compensator shows improved tracking performance compared with the existing model free controller in co-simulations.

Intelligent proportional trajectory tracking controllers: Using ultra-local model and time delay estimation techniques
This paper presents a new intelligent proportional control (iPs) for trajectory tracking of nonlinear affine-in control systems with unknown internal dynamics. The referred proposed controller whichExpand
Fast state estimation in linear time-varying systems: An algebraic approach
TLDR
An algebraic approach for state estimation of linear time-varying (LTV) systems is introduced based on Laplace transform, Leibniz formula, operational calculus and distribution theory, which results in a generalized expression of the state variables as a function of the integrals of the output and the input. Expand
Switching time estimation for linear switched systems: an algebraic approach
TLDR
This paper aims at estimating the switching time for linear switched systems, i.e. the time instant when a sub-model is switched on while another one is switched off, using a distribution point of view. Expand
Robust unknown input observer design for state estimation and fault detection using linear parameter
TLDR
A robust unknown input observer for state estimation and fault detection using linear parameter varying model and the convergence of the UIO is analysed by the Layapunov theory. Expand
