Photovoltaic (PV) water pumping system has been becoming increasingly important in remote, isolated, and non-electrified population, where either accessibility to the grid is difficult to establish or implementation cost is indeed very high. In such location, PV water pumping application is significant area of interest for sustainable development. In this article, DC and induction motor as part of multi and single stage water pumping system has been reviewed. The maximum power point (MPP) at which PV system is to be operated is tracked by peak power tracker to utilize solar power. Therefore, the peak power tracking algorithms with voltage, current, duty cycle, and frequency as perturbation parameters under uniform and non-uniform insolation are also presented. Review reports on PV emulators used for evaluation of new MPPT control techniques, and microcontroller based implementations of MPPT controller are also presented. Thus, this article becomes reference document for developing DC/AC PV water pumping system. (C) 2014 Elsevier Ltd. All rights reserved.

A single stage water pumping system comprises of a photovoltaic (PV) array, a controlled voltage source inverter, and an induction motor coupled with a water pump. It is highly efficient, low cost and easily controllable for water pumping application. The system characteristics are a predominant requirement for improving the performance. In this paper, the system behavior with six step mode, sinusoidal pulse width modulation (PWM) and space vector PWM (SVPWM) technique are studied. The system responses for different modulation indices are also reported. The characteristics for linear, centrifugal and optimized centrifugal pump load are determined. The experimental validation has been performed by implementing SVPWM employed with perturb and observe peak power tracking algorithm using dsPIC 6010A on a laboratory prototype. Thus, the system behavior proves to be high efficient, low cost and with simple control. Also, the selection of SVPWM with optimized v/f slope improves the performance of the system.

microcontroller-based simple maximum power point tracking controller for single-stage solar stand-alone water pumping system

PROGRESS IN PHOTOVOLTAICS 2013年第4期21卷 462-471页

作者： Packiam, P. Jain, N. K. Singh, I. P. Indian Inst Technol Delhi Instrument Design Dev Ctr New Delhi 110016 India

A simple microcontroller-based maximum power point tracking controller is proposed for a single-stage solar stand-alone water pumping system for remote, isolated, and nonelectrified population, where less maintenance, low cost, and an efficient system is of prime interest. It consists of a photovoltaic (PV) module, a DCAC converter utilizing space-vector pulse-width modulation, an induction motor coupled with a water pump, a voltage sensor, and a current sensor. A space-vector pulse-width modulation-controlled DCAC converter aided by a fast-acting onoff supervisory controller with a modified perturb-and-observe algorithm performs both the functions of converting PV output voltage to a variable voltage, variable frequency output, as well as extracting the maximum power. A limited variable step size is preferred during transient state, and a steady frequency, which is calculated on the basis of steady-state oscillation, is set during steady state. A fast-acting onoff supervisory controller regulates DC link voltage during steady state and enables maximum power point tracking algorithm only during transient state to draw a new voltage reference. In the event of low voltage, the controller switches off the motor but continuously scans for an available PV voltage. The system is not protected against an overcurrent because the maximum current is equal to its short circuit current. The 16-bit microcontroller dsPIC6010A (Microchip Technology, Inc., Chandler, AZ, USA) is used to implement the control functions. The proposed controller is verified through simulation as well as tested in the laboratory prototype model. The simulation and experimental results show good correlation.

Ball-Scorer is a differentially driven autonomous robot that was fabricated to compete in National Engineering Robotics Contest (NERC) 2008. This paper discusses the development of each component of the robot that is designed to pick up the balls from ball stand by navigating through a grid of white lines and potting these balls into goal posts of different heights. The sensory system of robot comprises of infrared sensors, potentiometers and bump switches. Three controllers namely proportional integral, proportional and proportional integral derivative are designed using root locus technique for navigation, ball picking and ball launching systems respectively. These controllers are then implemented using a single chip low cost AT89C52 microcontroller. Results are presented to show the validity and performance of the entire system. The robot can also be utilized in class room for teaching electromechanical and control systems principles.

In this study, a microcontroller-based gas mixture classification system is proposed to use real-time analyses of the trichloroethylene and acetone binary mixture. A Feed Forward Neural Network (FFNN) structure is performed for quantitative identification of individual gas concentrations (trichloroethylene and acetone) in their gas mixtures. The phthalocyanine-coated Quartz Crystal Microbalance (QCM) type sensors were used as gas sensors. A calibrated Mass Flow Controller (MFC) was used to control the flow rates of carrier gas and trichloroethylene and acetone gas mixtures streams. The components in the binary mixture were quantified by applying the sensor responses from the QCMs sensor array as inputs to the FFNN. The microcontroller-based gas mixture classification system performs Neural Network (NN)-based estimation, the data acquisition and user interface tasks. This system can estimate the gas concentrations of trichloroethylene and acetone with the average errors of 0.08% and 0.97%, respectively.

This paper describes the design and implementation of a modular architecture for distributed control of robot systems. The architecture is composed of autonomous modules; each module is equipped with a high-performance microcontroller, and has its own control functions with sensors, actuators, and communication interfaces as an intelligent autonomous sensing and actuating device. Operations of these autonomous modules are integrated through a communication network of serial bus type. For a mobile robot with two coaxial independently driving wheels, position and velocity control algorithms to follow a planned path cooperatively are implemented, and the performance of the proposed architecture is experimentally evaluated.
