to increase agricultural crops’ quality and to minimize losses in the final product and used energy during the drying process, major drying system parameters should be continuously controlled. precise control of such parameters is attained by using automatic control systems. to optimize the overall dryer efficiency in a forced convective solar dryer, a controller was designed, constructed a...
Recently, saving the cooling power in servers by controlling the fan speed has attracted considerable attention because of the increasing demand for high-density servers. This paper presents an optimal self-tuning proportional-integral-derivative (PID) controller, combining a PID neural network (PIDNN) with fan-power-based optimization in the transient-state temperature response in the time dom...
This paper presents the design and simulation of a novel fan speed control system based on room temperature using Pulse width Modulation Technique. The duty cycle is made to vary according to the room temperature and the fan speed is controlled accordingly. This paper elucidates how the autonomous speed control of fan is done based on data from the temperature sensor. The design proposed here i...
Wheat as a main food source is partly lost in different ways such as planting, harvesting, storage and even in consumption processes. This calls for attention to reducing these losses through application of the results from agricultural research, use of new farming practices, improvements in management system and repair and renewal of farm machinery. The present study considers the design, deve...

many factors affect yield loss in wheat harvesting with a grain combine harvester and there is no mathematical model to describe the behavior of this complex system. thus in this study, a fuzzy logic controller (flc) was designed, implemented and tested for the automatic settings of cylinder speed, concave clearance, fan speed and forward speed of a model 955 john deere combine. first, the mech...
Frequency converters provide means for the energy efficient flow and pressure control in pumping and fan systems by varying the motor speed. Besides speed variation, a modern frequency converter can estimate the state and performance of system operation without additional measurement sensors. This ability provides several possibilities to optimize pumping or fan system operation and the resulti...
Uncertainty quantification (UQ) has been achieved for the first time on the self-noise prediction of a low-subsonic axial fan. Realistic 5% and 4% errors are introduced on the volume flow-rate and the rotational speed, respectively, and a set of 81 ReynoldsAveraged Navier-Stokes (RANS) simulations of the fan mounted on an axisymmetric test plenum has been simulated at Clenshaw-Curtis points. By...
