In this work the advantage of FOPID controller over Conventional PID controller is discussed using MATLAB/Simulink. PID (proportional-integral-derivative) control is one of the earlier control strategies. Its early implementation was in pneumatic devices, followed by vacuum and solid state analog electronics, before arriving at today"s digital implementation of microprocessors. But in the last decade, fractional-order dynamic systems and controllers has been studying widely in many areas of engineering and science. The concept of the fractional-order PID controllers was proposed by Podlubny in 1997 . He also demonstrated the better response of this type of controllers, in comparison with the classical PID controllers, when used for the control of fractional-order systems. A method is presented based on idea of the Ziegler-Nichols and Cohen Coon for the tuning of PID controller. Motivated from the fact that the optimization techniques depend on initial estimates, Valerio and Costa have introduced some Ziegler-Nichols-type tuning rules for FOPIDs.

Here, model of a DC motor is considered as a second order system for speed control. In this work bio-inspired optimization technique in controllers and their advantages over conventional methods is discussed using MATLAB/Simulink. This proposed optimization methods could be applied for higher order system also to provide better system performance with minimum errors. The main aim is to apply PSO technique to design and tune parameters of PID controller to get an output with better dynamic and static performance. The application of PSO to the PID and FOPID controller imparts it the ability of tuning itself automatically in an on-line process while the application of optimization algorithm to the PID controller makes it to give an optimum output by searching for the best set of solutions for the ...

Here, model of a DC motor is considered as a second order system for speed control. In this work bio-inspired optimization technique in controllers and their advantages over conventional methods is discussed using MATLAB/Simulink. This proposed optimization methods could be applied for higher order system also to provide better system performance with minimum errors. The main aim is to apply ABC technique to design and tune parameters of PID controller to get an output with better dynamic and static performance. The application of ABC to the PID controller imparts it the ability of tuning itself automatically in an on-line process while the application of optimization algorithm to the PID controller makes it to give an optimum output by searching for the best set of solutions for the PID parameters.

It always finds the optimal solution to resolve its problem establishing perfect balance among its components. This is the driving force behind bio inspired computing. Nature inspired algorithms are meta heuristics that mimics the nature for solving optimization problems thus opening a new era in computation .For the past decades ,numerous research efforts has been concentrated in this particular area. Still being infantile and the results being very astonishing, broadens the scope and feasibility of Nature Inspired Algorithms (NIAs) exploring new areas of application and more opportunities in computing. This paper highlights the comparative analysis of nature inspired swarm Intelligence based o...

The nonlinearity in interconnected power system is primarily originated in the form of generation rate constraint and governor dead band (GDB). Out of these, GDB is the one due to which sustained oscillations may be observed in frequency of generated power. In order to mitigate these oscillations and to further provide robustness in control structure, a nested control structure (NCS), based on simple PID controllers, is proposed. Two different variants of NCS and a conventional PID controller are considered for the thorough comparative analysis in this paper. Further, the parameters of NCS and conventional feedback PID controller have been optimized with the help of a recently proposed bio-inspired salp swarm algorithm and its performance compared with particle swarm optimization(PSO). Extensive simulation studies presented in the paper establish that Salp swarm algorithm (SSA) optimized NCS provide significant improvement in dynamic performance of the system even under parametric variations with removal of sustained oscillations.
