development and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولexploring the relationship between iranian efl learners multiple intelligences, locus of control and reading proficiency
12 چکیده تفاوت های فردی، به عنوان خصوصیات روانشناختی غالب، باید در سطوح مختلف تدریس و یادگیری زبان کاملاً مورد ملاحظه قرار گیرند. از میان تاثیرگذارترین سازه های روانشناختی که منجر به تفاوت های فردی می شوند، می توان ازهوش چندگانه و منبع کنترل نام برد. هوش چندگانه با جنبه های متفاوتی از هوش سر و کار دارد که ممکن است هر شخص از آن برخوردار باشد. منبع کنترل، به عنوان مفهوم روانشناختی دیگر، به استن...
15 صفحه اولOptimal Control in Discrete Pest Control Models
We use discrete time models to represent the dynamics of two interacting populations, a “valuable” population and a “pest” population. We investigate optimal control in the form of decreasing the growth rate of the “pest” population with the goal of maximizing the “valuable” population while minimizing the cost of the control. We compare different types of growth functions for the “valuable” po...
متن کاملA Computational Method for Solving Optimal Control Problems and Their Applications
In order to obtain a solution to an optimal control problem, a numerical technique based on state-control parameterization method is presented. This method can be facilitated by the computation of performance index and state equation via approximating the control and state variable as a function of time. Several numerical examples are presented to confirm the analytical findings and illus...
متن کاملEconomic Injury Level (eil) and Economic Threshold (et) Concepts in Pest Management
One of the fundamental concepts of integrated pest management is that each pest species has a definable relationship in terms of damage to the plant or animal host that it attacks. This relationship is often referred to as the damage curve (Fig. 1), which is often determined relative to yield loss. This damage curve can take several forms, but was summarized by Higley and Peterson as having a t...
