<p>PROBLEM TO BE SOLVED: To improve both responsiveness and convergence properties of boost pressure in a control device for an engine.SOLUTION: A control device 1 for an engine for controlling a boost pressure by controlling an opening of a waste gate valve 17 includes setting means 2 for setting a virtual boost pressure Pcorresponding to an output request to the engine 10. The control device 1 further includes filter value calculating means 3 for calculating filter values P, Pin which filter processing that simulates transient response delay of the boost pressure is applied to the virtual boost pressure P. Moreover, the control device 1 includes: stationary time opening calculation means 4a for calculating a waste gate opening of the waste gate valve 17 for generating the virtual boost pressure Pas a stationary time opening R; and opening correction amount calculating means 4b for calculating a correction amount C of the waste gate opening relative to the stationary time opening R on the basis of a difference between the virtual boost pressure Pand the filter values P, P.</p> |
