G, EP And PSO Based Tuning Methods

The parameters of this controller (PI- 1) can be decreased during the voltage sag in order to improve the performance of the proposed method.

It is of great importance in our industries to cut the cost of power controlling with high efficiency and PWM satisfies this criteria. Therefore, it is

Using Field Oriented Control, current control is largely unaffected by speed of rotation of the motor[6].In the scheme of filed oriented control motor currents and voltages obtained from the motor are transformed into d-q reference frame. Measured currents from three stator phases these currents which are now in the stator reference frame are converted into two phase using Clarke transformations which are further converted into the corresponding rotor reference frame using Park transformation. The resultant current obtained is dc which is easier for the PI controllers to operate.

Abstract: Computer system performs tasks normally requiring human intelligence. For example: Decision making, speech recognition etc. Power system has been developed and updated to a very great extent. Even though it is updated, still there are many faults in transmission lines, distribution etc. To develop data, operator is used in the processing of data.The fundamentals of a modern control system is remote. Usually the power stations have a design which includes manual calculation, technical analysis which are less efficient methods when compared to these modern utilities used by the control system of power system.

Because of its linear characteristics and ease of controlling it's speed by simple power electronic circuit. The main obstacle for this type of system which has prompted the researchers to focus their studies toward AC machine, such as induction and synchronous machine. The availability of the variable speed drives for induction motor made it dominated in industry. Despite this, the small efficiency in induction motor especially those which have low power rating. The PMBDCM with predominant performance is found to be the solution for the drawbacks of the AC and Induction motors. The characteristics of the PMBDCM is similar to the separately excited DC motor, the difference in controller of PMBDCM which is the same of AC motor controller [2] [6].

The aim of this report to show the technical structure and lay out of research report it will show brief explanation off the chapters is to investigate some of the control options of the series and the parallel hybrid vehicle using In particular the simulation studies will be used to investigate the fuel consumption and energy use of the different hybrid structures.

The feedback control law presented in (21), linearizes the system input-output map and tracks the desired reference signal yR(t). Moreover, by applying (21), the closed loop system converts into e ̇=(A-BK)e , in

Abstract: In this paper multi machine concept is taken for fault ride through (FRT) improvement. Here FRT capability improvement of two wind generator are considered and two wind farms are connected with multi machine. This paper incorporates a detailed mathematical model for wind turbine and it shows how input wind is converted to power and how bet’z limit varies with wind. As a soft computing technique, fuzzy logic controller is used at grid side for voltage control. Crow bar protection concept is applied and implemented between machine and greed side converters. Ground fault is created in simulation and control technique helps to improve this FRT capability due to fault which we can say due to network disturbance.

This method does also suffer from the exploitative deficiencies like GA method, which could not precisely find the global optimum. Moreover, the original PSO is weakness in exploration that may results in local optimum. Therefore, some modified PSO may add a mutation process to ensure the global optimum.

In Fig. 7, it can be observed the non-convergence of TCOs and the random effects that arise depending on the relationship between dimensions. The non-convergence has a big influence on the controllability and on the stability of the controller. This has a big influence on the time spent to find the suitable combination and to

Abstract- This paper investigates the application of the Artificial Bee Colony Optimization (ABCO) algorithm based on PID control to Maximum Power Point Tracking (MPPT) of a PV system with energy storage powering DC motor-pump system during isolationand load variations. First, the total model of the entire system is obtained, including the PV, the boost converter, the storage system, and the DC motor-pump system. The controller performance with the proposed system is studied with a DC motor load deriving a pump of certain mechanical power. Moreover, the proposed system performance with the optimal approach in case of applying MPPT is compared with the system in case of operating without MPPT. The simulation results show that the performance of proposed system in case of operating at MPPT is improved by about 43% more than at operating without MPPT condition.

Abstract: In this paper proposed the fuzzy logic controller as an alternative solution of conventional PID controller for speed control of separated excited DC motor. Because many industrial applications need constant speed of a DC motor operation, such as paper mills, steel rolling mill…etc. But the various loads were effected on speed of DC motor, fuzzy logic controller gives better results in governing the speed control of SEDC motor, the paper used MATLAB/Simulink to simulation DC motor with fuzzy logic controller. The controller used seven memberships. Lastly, it’s found that the fuzzy logic controller provided better results for improving the dynamic behavior of SEDC motor.

In this study, a multi-input High Step-up Boost converter (MIHSBC) is proposed, which can not only deal with PV power and wind turbine energy simultaneously/individually but also with deal with Diesel generator and in addition, recycles the leakage-inductance energy and steps up the input voltage. As compared with the above-mentioned (Figure 2.) isolated double-input converter, the proposed one has a much simpler structure.
