Abstract
A controller () for an internal combustion engine includes: a calculation section () for calculating an angular acceleration or an angular velocity; an operational status-determining section () for determining an operational status based on the angular acceleration or the angular velocity; a gain-setting section () for setting a gain of torque based on feedback control; and a control section () for controlling the gain-setting section so that, when the operational status is a first operational status, the gain-setting section uses the angular acceleration as input data to set the gain (i), and when the operational status is a second operational status, the gain-setting section uses the angular velocity as input data to set the gain (ii).
