Patent ID: 8006548

Claim:
An engine bench system control system for an engine bench system in which an engine to be tested and a dynamometer are coupled together by a coupling shaft, and various kinds of characteristics of the engine are measured through a shaft torque control of the dynamometer, the engine bench system control system comprising: a controller that performs the shaft torque control of the dynamometer on a basis of a shaft torque command and a measured shaft torque of the dynamometer, with a transfer function expressed by the following equation, T ⁢ ⁢ 2 = K I s ⁢ ( T ⁢ ⁢ 12 ⁢ r - T ⁢ ⁢ 12 ) - K D ⁢ s + K P f 1 ⁢ s + 1 ⁢ T ⁢ ⁢ 12 , wherein T2 denotes a torque control signal, T12r denotes the shaft torque command, T12 denotes the measured shaft torque, K I , K D , K P , and f I denote parameters, and s denotes a Laplace operator.
