"This paper illustrates the application of hybrid\r\nmodeling and receding horizon optimal control techniques\r\nto the problem of air-to-fuel ratio and torque management\r\nin advanced technology gasoline direct injection stratified\r\ncharge (DISC) engines. A DISC engine represents an example\r\nof a constrained hybrid system, because it can operate\r\nin two discrete modes (stratified and homogeneous) and\r\nbecause the mode-dependent constraints on the air-to-fuel\r\nratio and on the spark timing need to be enforced. The paper\r\nextends the prior work by the authors [1] and reports the\r\ndevelopment of an explicit controller which implements the\r\noptimal solution using piecewise affine functions of the state, thereby avoiding the need for on-line optimization. Strategies to simplify the explicit controller by reducing the number of regions in its characterization are discussed."^^ . "2005" . "1" . . "IEEE"^^ . . "IEEE"^^ . . .
