Trends in the automotive control systems are toward more comprehensive and electronic control. The objective of this paper is to study the effectiveness of Internal Model Control PID (IMC-PID) method to develop a traction control system based on engine torque control for an automobile. A plant model is developed based on the governing equations and implemented in MATLAB. This is then captured in a Simulink model and simulated to evaluate performance of the open-loop system for both step and ramp inputs. A proportional-integral (PI)-type controller is then developed using IMC-PID tuning method to improve closed-loop system response. Finally, potential future applications and research opportunities are identified.

“…To derive the state space representation of the hydraulic wind power system, the integrated configuration of the hydraulic components must be considered. Nonlinear governing equations of utilized hydraulic components are provided in [17][18][19]. Using these equations, a nonlinear model of hydraulic wind power transfer systems are proposed in state space representation and experimentally verified.…”

Abstract__ Hydraulic wind power transfer systems deliver the captured energy by the blades to the generators differently and through an intermediate medium i.e. hydraulic fluid. This paper develops a control system for a nonlinear model of hydraulic wind power transfer systems. To maintain a fixed frequency electrical voltage by the system, the generator should remain at a constant rotational speed. The fluctuating wind speed from the upstream applies considerable disturbances on the system. A controller is designed and implemented to regulate the flow in the proportional valve and as a consequence the generator maintains its constant speed compensating for low wind speed and high wind speed disturbances. The controller is applied to the system by utilizing MATLAB/Simulink.

“…By applying the acceleration factor of 1.5 in average wind velocities per day [18], it will reveal that we had 240 days in 2007 which had an effective wind speed greater than the cut-in of the "FDCS-15B". Given the increase of the wind speed through the wind-arrester, as is calculated in (2), and the generation of 5760 hours a year, the installation of one smallscale wind turbine in 900 wind-arresters, which have adequate space for the selected wind turbine, across the town could generate the following output in one year as shown in (3). Moreover, the capacity of the hidden wind farm would be 504 kW as is calculated in (4 In this paper, a new concept has been defined for novel hidden wind farms in residential households having roof-mounted wind-arrester in Iran.…”

“…Iranian desert architecture enjoys a great number of traditional sustainable solutions in response to energy consumption within an arid climate, for instance, domes, water reservoirs, lofty walls and narrow streets [2]. One of the most effective solutions is to utilize the blowing wind in order to either generating power employing various proposed systems [3][4][5] or cooling a building. For the latter approach, the wind-arresters (bâdgir) have served as a passive cooling system for a long time, as is shown in Fig.…”

Abstract-Small-scale energy-generating systems are being increasingly integrated into built environment, and the use of renewable energies is now spreading to old towns in developing countries. Despite the promise of free energy, the high-tech appearance of the harnessing tools of renewables has provoked criticism because of the incompatibility with the cultural/environmental characteristics of older towns in Iran. This paper presents a new concept of novel hidden wind farms in the residential households of Iranian desert-edge towns with roofmounted wind-arresters. The results of this study show that a hidden wind farm integrated into old towns with the potential of tourism can eliminate the concern over the visibility and bird collisions as well as the use of land. In the present study, the old city of Ardakan, Yazd, with an arid climate located at the edge of a desert in the center of Iran, is selected as target case study. Calculations show that the application of one small-scale wind turbine per wind-arrester across the town can generate approximately 2.90 GWh a year. Moreover, the proposed concept could also be applied in other countries such as Afghanistan, Egypt, Pakistan, Iraq, UAE and some African countries.
