This paper presents a novel PID tri loop controller for a solar photovoltaic (PV) powered four-wheel drive electric vehicle using permanent magnet DC (PMDC) motors, which are modeled to include existing nonlinearities in motor plus load inertia (J) and viscous friction (B). A tri loop dynamic error signal generating algorithm is proposed to regulate motor(More)
A novel sinusoidal PWM switched power filter (SPF) and dynamic voltage compensation (DVC) scheme is studied in this work. A real time dynamic voltage, power and generator velocity error tracking based fuzzy logic controller (FLC) is used to stabilize the stand alone wind energy conversion scheme (WECS) comprising an induction generator. The novel dynamic(More)
This paper presents a novel multi-loop dynamic error driven controller based on the decoupled (d-q) voltage and current tracking loops for modulating the static synchronous compensator (STATCOM) used in distribution networks with dispersed renewable wind energy generation. The multi loop regulator adjusts the pulse switching pattern of the voltage-sourced(More)
This paper presents the modeling of a Fuzzy Logic Controller-Incremental (FLC-Inc.) based maximum power point tracking (MPPT) method and its comparison with traditional Perturb and Observation (P&O) method for standalone photovoltaic (PV) systems. The PV system, which is composed of PV panels, boost converter, MPPT unit and dc load, is modeled and(More)
In this paper, a novel heuristic search method called Gravitational Search Algorithm (GSA) is proposed for determination of the optimal proportional-integral (PI) and proportional-integral-derivate (PID) parameters in load frequency control of a single area power system. A single area non reheat thermal system is considered to design the PI and PID(More)
The paper presents a novel maximum utilization scheme for photovoltaic (PV) powered permanent magnet DC (PMDC) motor drives. The power from the PV array is used to operate the PMDC motor driving a mechanical pumping/ventilation/refrigeration load. The dc motor drive system is controlled by a dynamic multi-loop error driven proportional-integral-derivative(More)
In this paper, a Dynamic Voltage Regulator/Switched Power Filter (DVR/SPF) is proposed to overcome both power quality and voltage stability problems for single phase micro wind power generation systems. Beside the DVR/SPF a novel tri-loop dynamic error driven control structure is also proposed to be used in the filter control process. The total dynamic(More)
The paper presents a new Green Plug Filter Compensator and coordinated control strategy for Battery Powered Electric Vehicle. The integrated drive scheme is fully stabilized using a novel FACTS based green filter compensator developed by the Second Author that ensures stabilized DC bus voltage, minimal inrush current conditions and load excursions when load(More)
Photovoltaic PVA-solar powered electrical systems comprise different components and subsystems to be controlled separately. Since the generated solar power is dependant on uncontrollable environmental conditions, it requires extra caution to design robust tracking controllers that can handle unpredictable events to maintain dynamic source-load matching to(More)
