Abstract
A low order sampled data description of the response of output shaft torque to throttle opening is described. Based upon a sampling interval of one engine revolution, the resulting fourth order dynamic model is applicable over the range of 600-2000 rpm (vehicle speed 0-60 mph) for a 5.7 liter feedback carbureted engine and automatic transmission. Physical principles are used to set up a sampled data block diagram of the system and Landau's hyper stable identification algorithm is then used to determine the parameters of the model.
