In this paper, to ind a lower order model equivalent to a given higher order system, a simple method based on T.C Hsia's approximation method is proposed. To examine the accuracy of the proposed method, it is compared with the Hutton and Friedland's approach which uses α and β parameters. To demonstrate the correctness and efficacy of the proposed method, a fourth order system is reduced to first and second order using both the methods. The various performance indices of the reduced systems, obtained from the graphs plotted in Matlab platform are compared and analysed. © 2016 IEEE.

In this paper, the performance and design analysis of two different configurations of fractional order fuzzy logic controller (FLC) schemes are investigated for two-link planar robotic manipulator plant. The plant under consideration is carrying a payload which is varying with time. The scaling gains of FLC and the other parameters of controller are obtained using an efficient multi-objective optimization technique named as non-dominating sorted genetic algorithm-II (NSGA-II). Two different performance/objective functions are chosen for minimization to witness trade-off between them and to obtain better closed loop response. Using the MATLAB/Simulink platform for simulation, the performance of the proposed controller techniques are compared with the fractional version of PID (FOPID) and traditional Proportional-Integral-Derivative (PID) controller. For the robustness testing, the results for the disturbance rejections are presented for all the control schemes.

This paper presents a Proportional Integral Derivative controller based on Differential Voltage Current Conveyor Transconductance Amplifier as an active element. In the proposed circuit, the PID parameters namely, Proportional gain constant, Integral time constant and Derivative time constant can be tuned electronically by varying the bias current of the circuit. All the passive elements used are grounded, making it suitable for on-chip implementation. This circuit can be utilized to realize PI and PD controller. The simulations are done in OrCAD PSPICE with 0.5?m CMOS MIETEC technology . © 2016 IEEE.

In this paper, a Flyback-Forward converter employing a non-cascading scheme is presented in discontinuous conduction mode. The converter is designed to enhance the duty ratio of over 50%. As a result, the flyback sub-converter acts in boost mode and generates stepped-up output voltage. Since the switch utilization is required to be as high as possible in a forward converter, in present case, this objective is also simultaneously achieved. The simulation results obtained for a 24 V, 24W converter show the duty ratio greater than 50%. © 2016 IEEE.

A Novel controller for Model with Combined LFC and AVR Loops of Single Area Power System

In this study, a novel controller is designed to study low frequency oscillations for load frequency control (LFC) and voltage control of a single area power system. For more accuracy in dynamic and steady state responses, mutual effects between LFC and automatic voltage regulation (AVR) loops are investigated in a combined simulink model of LFC and AVR loops. The effectiveness of the proposed controller is first simulated on model with LFC loop alone. The proposed controller is a hybrid of neural network and fast traversal filters. The proposed hybrid controller requires less number of samples for training of weights, thus making the system fast. To study the coupling effects of AVR and LFC loops, dynamic performance of a complete system model for low frequency oscillation studies comprising of mechanical and electrical loops is done with the proposed controller. © 2014, The Institution of Engineers (India).

Metaheuristic or nature inspired optimization have evolved over time towards development of a general purpose optimizer. In this paper, a novel nature inspired algorithm, based on hunting mechanism of antlions, Ant Lion Optimizer toolkit is developed in LabVIEWTM environment. This paper provides an orderly procedure for development of toolkit including random walk of ants, building of traps, catching of prey and finally rebuilding of traps. LabVIEWTM is a highly productive development environment used largely in measurement and control applications. The only standard optimizer toolkit available in LabVIEW™ is Differential Evolution (DE) and therefore a need was felt to have an efficient optimizer. The toolkit so evolved in this paper when tested on different benchmark functions has performed adequately well over the DE toolkit. The results so obtained clearly prove that the submitted toolkit is able to provide superior results in terms of improved exploration, local optima avoidance, exploitation, and convergence.

The mathematical models used to represent physical processes are generally large and complex. Since simpler models are commonly employed in control, design and analysis, it is required to reduce the order of complex systems. This paper presents a comparative analysis of the performance of four order reduction methods. The computation of the lower order transfer functions is based on balance truncation algorithm, Hankel operator, moment matching and optimization algorithm. To demonstrate the performance of the reduction methods, second and third order transfer functions are computed for a plant model of fractional order. The integer transfer function of the plant model is obtained by applying Oustaloup filter approximation technique. For comparison of the reduction methods with ideal response, the analysis has been done both in frequency-domain and time-domain using MATLAB.
