Abstract:
1. A controller for an internal combustion engine, comprising: a calculation section for calculating an angular acceleration or an angular velocity of a crankshaft of a crank mechanism of the internal combustion engine; an operational status-determining section for determining an operational status of the internal combustion engine based on the angular acceleration or the angular velocity; a gain-setting section for setting a gain of torque that is required to operate the internal combustion engine, based on feedback control using the angular acceleration or the angular velocity as input data; and a control section for controlling the gain-setting section so that, when it is determined that the operational status is a first operational status, the gain-setting section uses the angular acceleration as input data to set the gain, and when it is determined that the operational status is a second operational status, the gain-setting section uses the angular velocity as input data to set the gain.
