The emergence of micro-sources in the energy market to reduce carbon emissions and exploit more renewable generations increases frequency oscillations system. Hence, this paper attempts develop a robust nonlinear fractional order proportional integral derivative (NLFOPID) controller for regulation restructured systems. A hybrid atom search-particle swarm optimization (AS-PSO) is proposed optimi...

Induction motors (IM) attracted many researchers in the last few decades. In this field, various applications are implemented, such as servo motor drives and electric vehicles. This work applies a sensorless direct torque controller (DTC) to control three-phase IM. System dynamics of IM were derived. A nonlinear dynamic model had introduced with white noise. Given complexity dynamics, Jacobean ...

This article is devoted to the fuzzy fault-tolerant tracking control of Markov jump systems with unknown mismatched faults. To reconstruct faults and system states, a sequence proportional–integral observers are established via outputs. With help structure separation technique, gains observer solved by unified linear matrix inequality framework. Resorting rebuilt states from an iterative estima...

In this paper a novel Hybrid Differential Artificial Bee Colony Algorithm (HDABCA) has been proposed for designing a fractional order proportional-integral (FO-PI) speed controller in a Permanent Magnet Synchronous Motor (PMSM) drive. FO-PI controllers’ parameters involve proportionality constant, integral constant and integral order, and hence its design is more complex than that of the usual ...

In this article, Load Frequency Control (LFC) of three area unequal interconnected thermal, wind and Hydro power generating units has been developed with ProportionalIntegral (PI) controller under MATLAB/SIMULINK environment. Further, the PI controller gains values that optimized using trial and error method with two different objective functions, namely the Integral Time Square Error (ITSE) an...
