Which is the speed at which the computer fan operates.

Width modulation based controllers, the performance of computer fan is investigated using the fuzzy logicĪpproach with two inputs parameters, that is, the computer loads and the temperature and one output parameter Unlike the popular PID controllers and the pulse

Logic approach as proposed by Lofti Asker Zadeh, popularized by the Japanese, has found its way into theĬontrol of many domestic and industrial appliances/machines. The impact of soft-computing in modern day engineering and technology cannot be overemphasized. The simulated and experimental results are compared. In this paper, Artificial Neural Networks (ANN) approach has been used for parameter estimation of a fan system. Further, fan system parameters estimation is required to ensure the smooth system operation and to avoid any malfunctioning of the system during abnormal working conditions. Therefore, fan system parameters are required to be estimated. resistances, reactances and some load parameters (fan blades).These parameters often change under varying operating conditions and the knowledge of these parameters is necessary to have optimum and efficient operation of the system. Basically, a fan is mainly consisting of a single phase induction motor and therefore fan system parameters are essentially the electrical parameters e.g. Fan parameters estimation is an important task as far as the reliable operation of a fan system is concerned. Electric Fans are very commonly used in the industries, domestic applications and in tunnels for cooling and ventilation purposes.
