We discuss one aspect of the allocation of new scientists to teaching and research careers. In the past, this allocation problem was treated on the basis of a model with kown constant parameters and as a classical open-loop optimal control problem with the allocation ratio as the sole control variable. The utility function in that treatment took both short term and long term goals into account....

This paper addresses a robust synchronization of fractional order unified systems whilst some parameters need to be identified. Based on the Sliding mode theory, a control law is proposed to realize a robust synchronization and parameter identification of two fractional order unified systems especially in presence of discrepancy in the initial conditions. This is also done when the slave system...

Recent advances in fractional order calculus led to the improvement of control theory and resulted potential use adaptive PID controller advanced academic industrial applications as compared conventional controller. Basically, a is an improved version classical integer that outperformed its counterpart. In case closed loop system, minute change would result instability overall system. An effici...

This paper is concerned with behavior analysis and improvement of wind turbines with Doubly Fed Induction Generator (DFIG) when using a new fractional-order control strategy during wind variations. A doubly fed induction generator, two types of variable frequency power electronic converters and two input wind waveforms are considered. A fractional-order control strategy is proposed for the wind...

nuclear power reactors are, in nature nonlinear and time varying. these characteristics must be considered, if large power variations occur in their working regime. in this paper a robust optimal gain scheduling controller for regulating the power of a nuclear reactor has been designed and simulated. the proposed controller is capable of regulating power levels in a wide power range (10% to 100...
