Modelling of Electromechanical Control of Camless Internal Combustion Engine Valve Actuator

  title={Modelling of Electromechanical Control of Camless Internal Combustion Engine Valve Actuator},
  author={Jeremiah Lekwuwa Chukwuneke and C. H. Achebe and Paul Chukwulozie Okolie and Obiora E. Anisiji},
This paper presents the modeling and control of internal combustion engine valve actuator mechanism, using variable valve actuation system, like electromechanical valve actuation system to flexibly control the engine valve timing and lift profile. In this paper, the prospects and possibilities of an electromechanical control of internal combustion engine valve to eliminate choking and backflow has been theoretically and technically analyzed. In principle, optimality in every engine condition… 
Comparative Analysis Between Cam and Cam-less Valve Actuating for Automotive System
This work modelled an Electromagnetic Valve Actuating (EMVA) system that captures a plant transfer function and a PID controller with a set-point tracking scheme and observed the camless system to outperform the cam system.
Investigation of the Effects of the Magnetic Circuit Design Parameters on the Electromechanical Valve Actuators
The paper describes the suitable type of magnetic circuits used in the electromechanical valve actuators (EVAs). Two different types of EVA models with the disc type of magnetic circuits were


Non-linear control of electromagnetic valves for camless engines
The soft–landing problem is translated into a regulation problem for the lift valve profile, by imposing that the valve position tracks a desired reference, while the modelled disturbances are rejected.
Modeling and Control of Electromechanical Valve Actuator
In this paper recent control developments for an electromechanical valve actuator will be presented. The model-based control methodology utilizes position feedback, a nonlinear observer that provides

Virtual Lash Adjuster for an Electromechanical Valve Actuator Through Iterative Learning Control
The reduction of impacts which occur in electromechanical valve actuators due to the presence of valve lash have been largely neglected in the literature. Instead, the majority of work in this area
Performance Evaluation of a Camless Engine Using Valve Actuators with Programmable Timing
An electronic valve timing (EVT) approach is described which utilizes high-speed, electropneumatic actuators producing nearly square wave valve lift profiles throughout the nominal engine speed
Model predictive control of magnetically actuated mass spring dampers for automotive applications
It is taken that model predictive control (MPC) and hybrid models can be an attractive and systematic methodology to handle these challenging control problems, even when the underlying process is not hybrid.
