Fuel cells guarantee ecological ways of electricity production by promising zero emissions. Proton exchange membrane fuel (PEMFCs) are considered one the safest methods, with a low operating temperature and maximum conversion efficiency. In order to harness full potential PEMFC, it is imperative ensure membrane’s safety through appropriate control strategies. However, most strategies focus on e...

In this paper, a class of uncertain linear systems with unmatched disturbances is considered, where the nominal system representation allowed to be non-minimum phase. A sliding surface designed which dependent on output, observed state, and estimated parameters. coordinate transformation introduced so that stability analysis reduced-order mode dynamics can conveniently performed. robust output ...

In this paper, chaotic dynamic and nonlinear control in a glucose-insulin system in types I diabetic patients and a healthy person have been investigated. Chaotic analysis methods of the blood glucose system include Lyapunov exponent and power spectral density based on the time series derived from the clinical data. Wolf's algorithm is used to calculate the Lyapunov exponent, which positive val...

In this paper; we are interested principally in dynamic modelling of quadrotor while taking into account the high-order nonholonomic constraints in order to develop a new synoptic control scheme as well as the various physical phenomena, which can influence the dynamics of a flying structure. These permit us to introduce a new statespace representation and a new control scheme. We present also ...

Abstract—This paper presents a robust control algorithm based on adaptive proportional-integral-derivative (PID) controller and sliding mode control (SMC) approach. In this paper, the drawbacks of SMC are compensated by adopting an adaptive PID continuous second order sliding mode control approach (APID2SMC) with PID sliding surface. The stability of the system is guaranteed in the sense of Lya...

This paper addresses the problems caused by an inappropriate selection of sliding surface parameters in fuzzy sliding mode controllers via an optimization approach. In particular, the proposed method employs the parallel distributed compensator scheme to design the state feedback based control law. The controller gains are determined in offline mode via a linear quadratic regular. The particle ...
