A control strategy was developed to improve fuel economy, enhance engine efficiency as well as extend battery cycle life in the series hybrid electric vehicle (SHEV) powertrain. The controller was based on fuzzy logic, fixedboundary-layer sliding mode controllers (FBLSMCs) and an optimized battery charge scenario. The fuzzy logic based energy management controller is developed to determine the ...

this paper presents a new control structure to reduce torque ripple in switched reluctance motor. although srm possesses many advantages in motor structure, it suers from large torque ripple that causes some problems such as vibration and acoustic noise. in this paper another control loop is added and torque ripple is de ned as an objective function. by using fuzzy sliding mode strategy, the dc...

This paper describes the new Engine Management System (EMS) ME7. Torque and A/F demands for modern EMS result from both, internal functions (i.e. engine start, idle speed control, catalyst heating) and external systems (i.e. driver’s request, transmission or vehicle dynamic control). With ME7 these demands are processed to the optimized actions of the actuators by a centrally coordinated torque...

Torque being a very important physical parameter, plays a very vital role in various applications like aviation, automobile, power and agriculture industries. Torque is, generally, measured by mechanical type torque meters/torque wrenches, having higher uncertainty. These mechanical type torque meters/torque wrenches need to be calibrated using strain gauged torque transducers. Hence, there is ...

As a response to the ever more stringent emission standards, automotive engines have become more complex with more actuators. The traditional approach of using many single-input single output controllers has become more difficult to design, due to complex system interactions and constraints. Model predictive control offers an attractive solution to this problem because of its ability to handle ...

The torque response of the engine is important for the driving experience of a vehicle. In spark ignited engines, torque is proportional to the air flow into the cylinders. Controlling torque therefore implies controlling air flow. In modern turbocharged engines, the driver commands are interpreted by an electronic control unit that controls the engine through electromechanical and pneumatic ac...

Rheology of the solid and melted cheese depends upon their functional properties. Farinograph is used for quality determination of wheat flour dough. Determination of the rheological properties of dough and dough like food materials from Farinograph is easy while study of cheese characteristics is very difficult and complicated. The present study is therefore designed for the possibility of qua...

Title of dissertation: THE IMAGE TORQUE OPERATOR FOR MID-LEVEL VISION: THEORY AND EXPERIMENT Morimichi Nishigaki, Doctor of Philosophy, 2012 Dissertation directed by: Professor Yiannis Aloimonos Department of Computer Science A problem central to visual scene understanding and computer vision is to extract semantically meaningful parts of images. A visual scene consists of objects, and the obje...

Torque-saturated control laws for spacecraft attitude control are considered. These control laws require no knowledge of the mass distribution of the spacecraft and thus are inertia-free. We examine two specific problems. In the first problem, the spacecraft has an arbitrary initial attitude and angular velocity, and the objective is to bring the spacecraft to rest with a specified attitude. In...

Various forms of electronic stability, traction and launch control have existed for over two decades, improving safety, sports performance and off-road capabilities of vehicles. These technologies involve individual control of each wheel’s drive torque or braking force in response to the dynamics of the driving conditions and the driver’s intentions. With the exception of launch control, applic...
