Thus, in this study, a centralized robust sliding mode controller is proposed to achieve minimum frequency deviation with optimal power distribution among distributed generations in an isolated microgrid. The microgrid model is developed for small signal analysis purpose using the electric vehicle charging model dynamics, the wind energy model dynamics and the run-of-river hydro model dynamics. The proposed controller parameters are optimized using linear matrix inequality (LMI), and its asymptotic convergence law is verified via Lyapunov’s stability theorem. The effective reduction in frequency deviations, time characteristics and chattering in control signals is achieved using the proposed controller. Furthermore, robustness nature of the proposed controller conforms against random plant outage sequence, random load and wind uncertainty. In addition, the performance of proposed controller is compared with existing state proportional–integral–derivative (PID) controller and traditional sliding mode control (SMC) even in presence of random plant outage sequence, load and wind speed uncertainties. The proposed controller is capable of regulating power share scenario intelligently according to load disturbance, plant uncertainties and also reducing time characteristics, oscillations and chattering phenomena in control effort within a short duration. As a result, the responses of proposed controller are compared with existing controllers in terms of improved closed-loop dynamics and its effectiveness. The performance of the proposed controller is demonstrated using MATLAB© simulations platform.

Audio-visual hysteria has created an eerie in the cases (clients) and living in phobia life. The self-motivated for psychological relief in their observed abnormal behaviors have contacted for counseling. Case-history and Online counseling session’s interaction was found that negative drive was developed in the clients and symptoms as suicidal tendency, Death phobia, Psychosomatic symptoms, Furious dream, Disorganized thoughts, Aggressive behaviors, Philosophical mind, and Financial insecurities were developed in the clients. Clients symptoms were validated by the Hamilton Depression Rating Scale (HDRS), some more symptoms were also identified by scale state-of-arts. The strength crisis was weighted by clients with Codes A (very high), B (average plus), and C (down t...

Focus is given on the heads of need for revival, self-reliance, the relationship between village and city, economic stability, modernization of dying skills, shifting paradigm on thinking, and standard recognition of past to future on the reviewed literature. A model was developed for making a path of analysis and experimentation in the future. The skills of traditional products should be discovered within the available resources in society and culture. Traditional techniques, methods, and methodology should be part of the higher education curriculum and recognized with the independent identity of the certificate, diploma, graduation, post-graduation, and research. Ethnic study and link with the market to the industry should be planned in the centers of higher education. More emphasis should be given to ski...

For this, geometrical spatial technique was used and measurement focus point was the eyes with reference of features, structure and colour. The interaction of eye shapes, forms , sizes and colours with different shapes of the face will produce 2160 real psyches Mathematically output is as : eye shapes are 10 , eye sizes are 3 , eye forms are 3 and eye colors are 3 ( only three have been selected on the basis of availability of sample identity ) and face shapes are 8 (10 x 3 x 3 x 3 x 8 = 2160 ) .Each psychological state was predicted in three forms as constructed psyche , manifested psyche and psyche that should be (real psyche). Thus, total 6480 (2160 X 3) psyche are to be identified. Determination of the psyche is based on the degree of associations between geometrical region of the face and eye alignments. Degree of predictability is a product of area of geometric...

In this study, a centralized nonlinear sliding mode voltage controller proposes to minimize the rotor and DC voltage oscillations issue in an islanded microgrid. The linear matrix inequality (LMI) technique has been applied for bounding the state error. Lyapunov criteria is utilized for assurance of asymptotic convergence and LMI optimization approach is used for obtaining the controller parameters. The proposed controller is able to tackle the parametric uncertainties of diesel generator, oscillations of rotor and voltage fluctuation as well as the closed-loop system responses also improves both transient responses and steady state responses simultaneously. The simulation results authenticate that the proposed controller confirms speedy recovery of nominal frequency without any oscillations and reduced the limitation of chattering notably without any loss...
