Abstract
A power generation system includes an internal combustion engine, an electrical generator, and a power transmission mechanism. A method for controlling the system includes executing rotation speed control of driving the electrical generator by using electric power supplied from a battery, and matching a rotation speed of the electrical generator with a target rotation speed at the time of starting the power generation system. Output possible electric power of the battery and rotation speed of the electrical generator are acquired. A filtering process of reducing a component of a resonance frequency band of a spring-mass system including the engine, generator, and power transmission mechanism is executed on the rotation speed of the electrical generator. An upper limit torque of the electrical generator is calculated based on the filtered rotation speed and the output possible electric power. The rotation speed control is executed under a limitation of the upper limit torque.
