This work focuses on
photovoltaic array fed sewing machine. Main focus is on utilizing non
conventional energy resources i.e. solar energy because now-a-days the
entire world is facing crises of energy. System consists of an
arrangement of several components, including solar panels to absorb and
convert sunlight to electricity. In this research work a photovoltaic
array is used to run a motor i.e. dc motor that drives the sewing
machine. Dc motor will be fed by charge controller and the duty cycle of
charge controller is controlled by using MPPT (P&O) algorithm. The
simulink model of the research work is done using MATLAB software.
Presently, classic PID control theory is mainly adopted in the research on speed control of the motor servo system of ISM. Based on the classic PID control theory, increment-PI control algorithm or fuzzy PID control theory are also adopted in this research field
The system function is the selection of small and medium electric motors. When the users input the certain known motor parameters, one or more motor models selected in the system will be showed. This kind of problem that has data-driven feature is suitable for the rule based language with forward inference. The typical case is reading in one group of motor parameter the each program cycle and deducting until obtaining all the possible conclusions according to input data. jack sewing machine dealers in chennai
The unification of data is a very important step in this system. That means at the stage of setting up the knowledgebase, some motor parameters have been systematically standardized and can be recognized by the system. Taking the speed control for example, each user may have their specific requirements of speed. To be exhaustive, some fuzzy selection functions will be lost and the user's choice will be limited. Therefore this paper will categorize the speed range to high, low and none ((speed range high), (speed range low), (speed range zero)).This not only facilitates the establishment of the system, but also makes the selection of speed easier. When the users choose the speed, they don’t need to consider the actual data and all they need to know is the scope of the speed range. After the data standardization is finished, the rule is needed to control the data. The rule verifies the match degree of the input data and the knowledgebase by pattern matching .
