Abstract
- Engines with variable poppet valve timing systems are among numerous efforts that aim to reduce engine emissions and/or increase efficiency. In the present paper we have investigated the stability of a magnetic valve system in MATLAB. First we designed the magnet and interactive forces inside the electromagnetic valve system, then we produced a mechanical model for the system by using a two degree of freedom mass and spring system and finally designed a PID controller to maintain system stability. The results of the present study indicate that the controller had decreased the maximum valve displacement domain and duration from 2 mm to 0.001 mm and 0.1 seconds to 0.022 seconds, respectively. Poppet valve settling speed was 0.0126 and had a standard deviation of 0.1304 while the armature settling speed was 0.0184, with a standard deviation of 0.1363. Passes for the phases were -37.5 and -169, with gains of 10.3 and -9.35. [ABSTRACT FROM AUTHOR]
