RISModel-Based Control for Mode Transition Between Spark Ignition and HCCI Combustion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: While the homogeneous charge compression ignition (HCCI) combustion has its advantages of high thermal efficiency with low emissions, its operational range is limited in both engine speed and load. To utilize the advantage ...
Experimental Study on an Electric Variable Valve Timing Actuator: Linear Parameter Varying Modeling and Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents experimental investigation results of an electric variable valve timing (EVVT) actuator using linear parameter varying (LPV) system identification and control. For the LPV system identification, a number ...
A Control Oriented Two Zone Charge Mixing Model for HCCI Engines With Experimental Validation Using an Optical Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A controloriented twozone charge mixing model is developed to simplify, but to describe mixing of fresh charge and residual gas during the intake stroke. Engine valve timing has a strong influence on the realization of ...
Linear Matrix Inequalities Approach to Input Covariance Constraint Control With Application to Electronic Throttle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the input covariance constraint (ICC) control problem is solved by convex optimization subject to linear matrix inequalities (LMIs) constraints. The ICC control problem is an optimal control problem that is ...
