In this paper we have applied two types of control on two coupled water tanks, where the dynamic model is nonlinear system. The first control is the sliding mode with linear surface, the advantages of this type of control is the discontinuity behavior which can be applied to variable structure systems (VSS) and its good robustness against the injected disturbances, and/or the noise, and finally unaffected...
This paper presents an improvement algorithm of Model Predictive Control (MPC) for the quasi Z-Source Inverter (qZSI) with a standalone system. The improved algorithm decreases number of the desired sensors from five into three, where it just needs two current sensors for measuring the AC currents, and another voltage sensor for capacitor voltage detection. The inductor current will be estimated according...
In this paper, a complete characterization of the continuous state observability is derived for serial multicellular converter based on hybrid systems approach. More precisely, a necessary and sufficient condition for the continuous state observability for a given switching signal is elaborated for n-cell converter. Concrete examples are reported to highlight the derived results.
In this paper we consider the problem of the stability of switched nonlinear systems. We use an optimization strategy based on Linear Matrix Inequality (LMI) and a genetic algorithm (GA), to compute the region of attraction of each subsystem. The feedback control will be designed to guarantee global stability by means the multiply Lyapunov functions under a switching signal. The implementation and...
This work is a study, analysis and implementation of the indirect space vector modulation for three to three phase matrix converter. The input factor is fixed to zero, an over modulation is presented. The algorithm is implemented on dSPACE 1104 with real voltage sensors and an acquisition of the results using control desk and oscilloscope is presented.
This paper deals with macroscopic traffic modelling. It investigates real magnetic sensor data, provided by the Performance Measurements System (PeMS), in order to identify some traffic parameters related to a portion of the SR60-E highway in Califorina. Then, these parameters are used to validate a switched linear traffic model.
In this paper, an observer for Switched Linear Systems (SLS) with unknown inputs is designed. LMI conditions, guaranteeing the asymptotic convergence of the observer derived through multiple Lyapunov functions and LMI region. This is done by decoupling a subset of the system states from the unknown inputs and by estimating the states thanks to a like Luenberger observer. Then, an estimator for the...
The aim of this paper is to propose a generalization of our previous work on practical stabilizing method and switched observer for (low power) single switch DC/DC converters. Generally, the subsystems in PWA models that represent these converters do not share any equilibrium or may not have any one, so that, no strict convergence to any average equilibrium is expected. For this reason, we have opted...
This paper is about the development of an experimental matrix converter drive and its application to electrical three-phases motors. Theoretical and practical information are given in order to help researchers to reproduce such a bench. The system is applied to an induction motor to show its effectiveness.
This paper concerns the Fault Detection and Isolation (FDI) problem for a class of Switched Linear Systems (SLS) subject to sensor faults and unknown bounded disturbances. The main work is based on the design of a generalized switched observer scheme. The FDI problems have been solved by using a robust control techniques. A suitable trade-off between the robustness to disturbances and the sensitivity...
