Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...

This paper addresses the design of control charts for both variable ( x chart) andattribute (u and c charts) quality characteristics, when there is uncertainty about the processparameters or sample data. Derived control charts are more flexible than the strict crisp case, dueto the ability of encompassing the effects of vagueness in form of the degree of expert’spresumption. We extend the use o...

In the paper the optimization of the control loops of the variable frequency induction motor drive for the feed screw of a flame reactor has been carried out to obtain required dynamic characteristics of the electric drive for known parameters of the plant. Simulation studies of basic control loops (current, flux-linkage and speed) are performed and dynamic parameters of control quality are pre...

ISSN 2250 – 1088 | © 2011 Bonfring Abstract--This paper describes active power control in a grid connected variable speed wind electric generation system (WEG) using squirrel cage induction machine. The chosen variable speed WEG system consists of a wind turbine, squirrel-cage induction generator, an AC-DC-AC interface and the power grid. In this work the generator side converter is controlled ...

In this paper, the Takagi–Sugeno (T–S) fuzzy model is used to express dynamic systems, and an on-line identification algorithm for its parameters and structures is presented. A new multivariable fuzzy generalized predictive control approach is put forward based on the identified fuzzy model by means of Clark’s principle of single-variable generalized predictive control, some of whose performanc...

This paper identifies weak points in the control of commercial DC variable-speed compressors, fed by photovoltaic panels, and describes the development of an energy-efficient control method. The method can be used in any application requiring such compressors to be driven by PV's, either for heating or cooling purposes. The advantage of using the presented method is the improved utilization of ...

In electric drive control systems, the main goal is to maintain driving motor speed meet mechanism’s requirements. some practical industrial applications mechanically-coupled load shaft has a varying mass during system operation. Therefore, change of changes value moment inertia system. The impacts operation, particularly transient performance. variation on its operation creates additional chal...

Among HEV configurations, the electronic-continuously variable transmission (e-CVT) architecture can optimally blend power from an engine and electric motor/generators. Design of an e-CVT powertrain is a challenging and timeconsuming task due to the system complexity and the multidisciplinary nature of the design problem. In this work, an approach to develop the system-optimal based instantaneo...
