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 engine 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
