Semi-physical mean-value NOx model for diesel engine control

In this paper, a new physics-based model for the prediction of NOx emissions produced by diesel engines is presented. The aim of this work is to provide a Mean-Value Model (MVM) adapted for control design and online estimation. The proposed approach is based on the simplification of a zero-dimensional thermodynamic model. Only the main phenomena taking part in NOx formation are kept and they ar...

Modeling and Optimization Control for Aircraft AC Generator Brushless Excitation System Based on Improved Adaptive PSO

The brushless excitation system of aircraft AC generator is a strong coupled and nonlinearity dynamic system which is often being subjected to disturbances. Therefore, the conventional PID controller is unable to meet the brushless excitation system control requirements of More Electric Aircraft (MEA) or All Electric Aircraft (AEA). A new brushless excitation compound control controller (RBFPID...
