Analyzing The Electromechanical Valve And The Benefits...

CAMLESS ENGINES AND THE BENEFITS THEY PRODUCE The authors of the reviewed article are: Marcello Montanari, Fabio Ronchi, Carlo Rossi, and Alberto Tonielli, all of whom are members of IEEE (Institute of Electrical and Electronics Engineers). Marcello Montanari received the Laurea degree in computer science, engineering, and a Ph.D. in automatic control from the University of Bologna, Bologna, Italy, in 1999 and 2003. Since 2000, he has been with the Department of Electronics, Computer Science and Systems (DEIS), University of Bologna. His current research interests include applied nonlinear and adaptive control techniques, electric drives, and automotive systems. His co-authors are also graduates of the University of Bologna and are members†¦show more content†¦SUMMARY In Montanari’s article first, he addresses and formulates the problem. Second, he creates a mathematical model of the system, and analyzes the requirements for the controlled system. Third, he completes the position reconstruction and the analysis of the sensors. Lastly the reference of trajectories for the pistons, to ensure the stability of the system, is completed. After all this Montanari proposes a control system architecture for the position control of an electromechanical valve actuator. There are two key parts of the controller, specifically, the position reconstruction, and the reference trajectory design. Both of these have been addressed, and the resulting limitations on the system’s dynamic performance explained. Knowledge of these limitations is essential when integrating a valve actuation system within the internal combustion engine management system. Hence, the results presented in this paper are an important step toward the realization of a Camless engin e with electromechanical actuators for commercial vehicles. Camless engines offer a lot of improvements over traditional engines in efficiency, maximum torque and power, and emissions. Electromechanical valve (EMV) actuators are a great way to solve this problem, but electromechanical valves have major
