IDCS制御手法を用いたタイヤ-サスペンションHILSシステムの再現性向上

抄録

In the development of an automobile, various testing systems with hardware-in-the-loop simulation (HILS) techniques are proposed. Tire-suspension HILS system was a hybrid method with vehicle dynamics analysis and bench test of the tire-suspension system. The accuracy of an actuator control of the testing machine is significant for this system. In this paper, we proposed the tire-suspension HILS system with new actuator control using inverse dynamics compensation via ‘simulation of feedback control system’ (IDCS). IDCS is a numerical method to obtain an approximate inverse dynamic via feedback control simulation, using only the forward dynamic model of the system. The multibody dynamics model of the testing machine was used as the forward dynamic model and the suspension behavior of the vehicle dynamics analysis was reproduced by the actuator in the testing machine.
