A nonlinear controller of a turbocharged diesel engine using sliding mode

This study seeks to apply sliding mode control to a turbocharged diesel engine. A complete physical model followed by a reduced form and taking into account thermodynamics of the different steps of the diesel cycle has never been proposed in the literature. The study shows the role of the turbocompressor on the cylinder filling during the air intake and the exhaust phases on different engine states through thermodynamic laws. This is an attempt to describe the dynamics of the diesel engine by physical equations. The sliding mode control method is used and a solution to the multivariable system control problem is presented. A compressor power control approach is used and relationships between fluid states in the air intake and the exhaust manifold pressure are discussed.
