| Abstract(J) | 自動車製造業界においては約5年前以降，実際の能動的懸架装置についてのそれよりもアクチュエータ内部の動的挙動の解析につき，より多くの研究が行われている．そこで今回は，アクチュエータならびにその内力制御ループを検討の中心的な対象として行った研究や各種の調査，および論議などの概要について報告した． Translation |
| Abstract(E) | For a hydraulic force control, the relative velocity of the jack could be viewed as a perturbation and leads to some dynamic discrepancies in the controlled force realization. The linear analysis proves that a PI controller can not really compensate or eliminate this perturbation. A new control law is presented based on two main ideas : a perturbation rejection technique to eliminate the sensitivity of the force control on the jack relative velocity and a kind of linearizing technique by inverting the Bernoulli flow characteristics of the valve. In theory these two techniques lead the system to a very simple one easy to control with a constant proportional gain. Two non linear laws are introduced : one in open loop and one in closed loop system. Both of them give quite good results but some problems still remain like valve dynamics effects, valve underlap/overlap, zero force input. |
