Pressure control of a two-stage turbocharged diesel engine using a novel nonlinear IMC approach

This paper deals with nonlinear multivariable output feedback control of a two-stage turbocharged diesel engine. The feedback structure of internal model control (IMC) is used in combination with a nonlinear feedforward controller based on geometric nonlinear control design methods. Input saturations as well as measured disturbances are taken into account and a severe rank deficiency is handled. This novel control approach is the first model-based solution to this problem and results in impressive control performance
