Abstract
A control system for a chassis dynamometer has a computing circuit which computes the gradient of an evaluation function on the basis of outputs of a torque sensor and a speed sensor provided on a shaft directly connecting a roller and a dynamometer and a sequential correction computing circuit of feedback control circuit. The steepest descent method is used so as to reduce the evaluation function to a minimum and to thereby sequentially compute the predicted output values of said dynamometer. The control system for the dynamometer is stable and superior in its quick response and simple in its circuit construction.
