PURPOSE:To highly accurately conduct a performance test of an engine, motorcar, etc., by providing an running pattern generator, an operation processing part providing a throttle forecast opening operating part, and a fuzzy correction controlling part. CONSTITUTION:A revolution N-torque T-throttle opening theta map of an engine E to be tested is prepared to be stored, the set revolution and throttle opening theta1 from a running pattern generator 5 are computed from the map in a throttle forecast opening operating part 1, and the throttle opening corresponding to the angular acceleration of the engine E is operated by a part 2 for operating the acceleration equivalent in a throttle opening. The set revolution, the opening theta1, and a throttle opening theta1 of the angular acceleration are added to it in an adder 3, and the added value is inputted to a throttle amplifier 9. The difference of the set revolution.torque and the real one is controlled as deflection correction in a fuzzy correction controlling part 7, and theta1+theta2+theta3 added in an adder 8 is fed back to a throttle actuator 10 as the set value of the last opening, and the throttle of the engine E is actuated by the amplifier 9.
