Optimal Torque Control for an Electric-Drive Vehicle with In-Wheel Motors: Implementation and Experiments

© SAE, Athari, A., Fallah, S., Li, B., Khajepour, A. et al., "Optimal Torque Control for an Electric-Drive Vehicle with In-Wheel Motors: Implementation and Experiments," SAE Int. J. Commer. Veh. 6(1):82-92, 2013, doi:10.4271/2013-01-0674.This paper presents the implementation of an off-line optimized torque vectoring controller on an electric-drive vehicle with four in-wheel motors for driver assistance and handling performance enhancement. The controller takes vehicle longitudinal, lateral, and yaw acceleration signals as feedback using the concept of state-derivative feedback control. The objective of the controller is to optimally control the vehicle motion according to the driver commands. Reference signals are first calculated using a driver command interpreter to accurately interpret what the driver intends for the vehicle motion. The controller then adjusts the braking/throttle outputs based on discrepancy between the vehicle response and the interpreter command. A test vehicle equipped with four in-wheel electric motors, vehicle sensors, communication buses, and dSPACE rapid prototyping hardware is instrumented and the control performance is verified through vehicle handling tests under different driving conditions.Automotive Partnership CanadaOntario Research FundGeneral Motor

Spinal tuberculosis: diagnosis and management.

The spinal column is involved in less than 1% of all cases of tuberculosis (TB). Spinal TB is a very dangerous type of skeletal TB as it can be associated with neurologic deficit due to compression of adjacent neural structures and significant spinal deformity. Therefore, early diagnosis and management of spinal TB has special importance in preventing these serious complications. In order to extract current trends in diagnosis and medical or surgical treatment of spinal TB we performed a narrative review with analysis of all the articles available for us which were published between 1990 and 2011. Althoug h the development of more accurate imaging modalities such as magnetic resonance imaging and advanced surgical techniques have made the early diagnosis and management of spinal TB much easier, these are still very challenging topics. In this review we aim to discuss the diagnosis and management of spinal TB based on studies with acceptable design, clearly explained results and justifiable conclusions

The Philosophical Underpinnings of Trump\u27s Foreign Policy: Analyzing Key Influences and Implications

Donald Trump, the forty fifth President of the United States, has attracted and continues drawing sharp criticism regarding his foreign policy. Apart from being described in some circles as a nationalist, there is no denying that the President holds an extraordinary set of beliefs that are completely different from the rest of the world and dedicates himself to achieving them regardless of any type of backlash. ‘America First’, Mr Trump’s campaign slogan, sends messages which offer a glimpse to the intertwining principles of his policies and strong anti-globalist sentiment of the American people which results in a revolutionary view of a world order that focuses on restraint and traditionalism. In this scientific commentary, we will discuss the basic philosophical formatives that are guiding Trump\u27s foreign policy and explaining how this world\u27s perceptions not only impact the President\u27s decisions, but also the international relations as a whole. Furthermore, we explore what this means for the wider understanding of politics where ideology and practice grow in opposite directions. We trust this will provide useful insights into what to expect out of US diplomatic relations in the subsequent years after the end of Mr. Trump’s presidency
