The Individual

Recent performance analysis techniques have attempted to move beyond a narrow focus on game outcomes by considering the game, team, group and individual tactical levels. Goals are decisive in football, yet the extent to which the individual goalkeeper had been studied was unknown. We therefore systematically searched the literature to determine the extent of studies that included actions related to the goalkeeper; of 711 titles retrieved, six met the full inclusion criteria. Despite sound study design in general, the use of World Cup matches might limit the generalisability of findings. Only 21% of the outcome variables extracted were comparable across studies, with 58 different variables used to describe actions involving the goalkeeper, which suggested significant conceptual disparity. Of greater concern, no studies presented the striker and goalkeeper interaction in relative terms. The development of an analytic model that quantifies this relationship is necessary to adequately characterise tactics and inform the practical requirements of goalkeeping tactical training.

<p>This study presents a performance analysis of two most popular control strategies for Induction Motor (IM) drives: direct torque control (DTC) and space vector modulation (SVM) strategies. The performance analysis is done by applying field-orientation control (FOC) technique because of its good dynamic response. The theoretical principle, simulation results are discussed to study the dynamic performances of the drive system for individual control strategies using actual parameters of induction motor. A closed loop PI controller scheme has been used. The main purpose of this study is to minimize ripple in torque response curve and to achieve quick speed response as well as to investigate the condition for optimum performance of induction motor drive. Depending on the simulation results this study also presents a detailed comparison between direct torque control and space vector modulation based field-orientation control method for the induction motor drive.</p>
