Conventionally, production system modeling (PSM) has been conducted for the purpose of steady-state analysis, which only facilitates characterizing the long-term performance of production systems. More recently, there has been a rising concern regarding analyzing production system transients, which depict the system behavior before reaching the steady state. Transients are generally undesirable because...
A state space finite element method is presented for the calculation of transient electric field in oil-immersed insulation system of converter transformer. Firstly, the state equation is derived based on the quasi-static electric field theory, combined with the given boundary value using the penalty method, which has a clear physical meaning. Secondly, the state equation is solved in a fine integration...
During the gasoline engine transient process, both fuel quantity and fuel film parameter change, fuel film dynamics balance in intake pipe is destroyed, which makes the fuel quantity from nozzle and fuel quantity into the cylinder not be equaled. Therefore, fuel film model need to be established accurately in order to control the air fuel ratio accurately. The costumed fuel film model of Aquino is...
