This paper presents average torque control schemes for switched reluctance motors based on current control. For the purpose of finding the optimal switching point with proposed controller, It is utilized turn on and turn off position calculation with current controller. The goal of proposed paper is the maximisation of the energy conversion per stroke and maximising efficiency and obtaining approximately flat-topped current waveform. The proposed control scheme is demonstrated on a simulation with Matlab Simulink.

To use land of area that land price hike is less as is serious being population centralism of big city by economic growth maximum, high building is making much. However, existent vertical carrier system has application height difficult a lot of controversial points in the High building. Specially, method that depend on iron vessel weight of line a lot of weights occupy and can increase ratio that vertical carrier system occupies gross area of building as height of building is high lineally and increase to maximum 30%. I wish to apply linear induction motor that is not existent vertical carrier system to solve these problem and design carrier system.

Solar cell converts sunlight into the electricity that one of the most versatile forms of energy. It has been developed and applied on residental electric power system by urbanized countries as a alternative energy source to overcome energy problem after oil shock. This paper summarizes the results of these efforts by offering a snapshot of the configuration of photovoltaic in residential applications. The status of PV system components and inter -connection and safety equipment will be summarized. Hence this paper discusses only points that might be useful for application.
