This paper deals with the design and evaluation of a robust controller for static VAR compensator (SVC) in remote industrial power systems to enhance the voltage profile for three-phase single cage induction motor (SCIM) loads. The controller design is based on H∞ theory to deal with uncertainties arising in industrial network modelling. &#10The performance of the H∞ controller has been evaluat...

In this study, we intend to show the basis of a general legged locomotion controller with the ability to integrate both posture and rhythmic motion controls and shift continuously from one control method to the other according to the walking speed. The rhythmic motion of each leg in the sagittal plane is generated by a single leg controller which controls the swing-to-stance and stance-toswing ...

The interline power flow controller (IPFC) is a concept of the FACTS controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. This paper proposes a novel IPFC-Based Damping Neuro-control scheme using PSO for damping oscil‌la‌t‌i‌o‌ns in a power system to improve power system stability. The add‌i‌tion of a supplementary controll...

This thesis proposes a novel digital method for optimization and adaptation of control systems representable In the phase plane. By continually generating Its own optimum trajectories the digital controller has sufficient Intelligence to discern optimum switching points and system parameter changes. The optimum trajectory Is stored in memory as error addressed to memory position by a pseudo err...

FACTS technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. STATCOM is oneof the most important FACTS devices used in the parallel compensation, enhancing transient stability andetc. Since three phase fault is widespread in power systems, in this paper STATCOM is used...

In this paper, tuning of power system stabilizer (PSS) and thyristor controlled series capacitor (TCSC) is studied. The analysis of mode controllability is used to select the effective location for TCSC. The performances of TCSC equipped with a proportional-integral-derivative controller (P-I-D controller) and proportional-integral-derivative power system stabilizer (P-I-D PSS) are investigated...

In this paper, a fault-tolerant three-phase induction drive based on field-oriented control is studied, and an analytical approach proposed to elucidate the limitations of FOC in flux-torque regulation from controller perspective. With open-phase fault, disturbance terms appear reference frame degrade performance when operating d-q plane with DC quantities. addition, hardware reconfiguration, w...

this paper proposes a flexible power electronic transformer (fpet) for the application in the micro-grids. the low frequency transformer is usually used at the point of common coupling (pcc) to connect the low voltage grid and utility network to each other. the conventional 50hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. in this pap...

The architectural principles of Software-Defined Networking (SDN) and its most prominent supporting protocol OpenFlow keep gaining momentum. SDN relies essentially on the decoupling of the control plane from the data plane, placing the former in a logically centralized component to be executed on commodity hardware the SDN controller. OpenFlow’s reactive programming enables the programming of t...

In the present paper, the problem of computation of all stabilizing high-order time delay systems using well known and efficient proportionalintegral-derivative (PID) controller is investigated in a graphical approach. An efficient approach to this important problem is presented. Based on this approach, all PID controllers that will ensure stability are determined in a ) , , ( d i p k k k plane...
