...-to-state stability. Lookup tables, which are widely used to represent the complex nonlinear characteristics of engine systems, appear in their original form in the designed reduced-order observer, and the torsional stiffness of the drive axle shaft is considered in the model-based design procedure...

... engine, horizon-based optimization methodologies should be used because the light-off of the three-way catalytic converter heavily depends on the warming-up of catalyst temperature. In this paper, we propose a systematic design method for a cold-start supervisory control algorithm based on the dynamic...

...Jason A. Meyer; Stephen Yurkovich; Shawn Midlam-Mohler One of the most overlooked and oversimplified components of an engine model used for model based air-to-fuel ratio (AFR) control and/or diagnostics is the exhaust gas dynamics model. Without a proper model of the exhaust system, the mixing...

..., which are directly related to the engine firing orders. In order to achieve a more comfortable environment and pleasing driving experience, an active noise control (ANC) applying advanced filtered-x least mean squares ( FXLMS ) algorithm is employed to reduce the vehicle interior noise by targeting...

... years for the energy capacity to compare with fossil fuel driven powertrains. Full hybrid technology by contrast still needs a significant increase in IC engine efficiency and a substantial reduction in cost, weight, and complexity. To accelerate the take-up of Option-1, range-extenders are being fitted...

...Mahdi Shahbakhti; Charles Robert Koch Incorporating homogeneous charge compression ignition (HCCI) into combustion engines for better fuel economy and lower emission requires understanding the dynamics influencing the combustion timing in HCCI engines. A control oriented model to dynamically...

...Tiebao Yang; Xiang Chen Feedback control has been pursued to stabilize the bifurcated operating solution near the rotating stall point in axial-flow compressors. These controllers can extend the stable operating range and hence improve engine performance. However, the local L 2 gain...

... to perform the switching of three functions arbitrarily: automatic LATC, manual drive-by-wire, and pure manual operation. Then, a nonlinear dynamics model for the test vehicle is proposed by using a state-space equation, and several major nonlinear components including the engine, torque converter...
