    摘要: This paper presents an intelligent control strategy for an active MacPherson suspension driven
    by a pneumatic muscle (PM) actuated system and evaluates its improved control performance on a selfdeveloped test-rig. To fulfill the fully-functional test and analysis of active suspension systems, this test-rig
    comprises three units: 1. an active MacPherson suspension unit, which consists of a PM mechanism and two
    MacPherson struts, is built to isolate vibration from road disturbances; 2. a road profile generator (RPG)
    unit, which can produce a vertical force to lift the car-body according to various road profiles; 3. a PC-based
    control (PBC) unit, which computes, sends and receives signals for both of the active MacPherson suspension
    and the PC-based control unit. The objective of this study is to improve the MacPherson suspension in
    terms of the capability of road vibration isolation by using the PM actuation that can actively provide extra
    compensatory force for MacPherson struts. Then, for motion control of the PM, this study employs an
    interval type-2 adaptive fuzzy controller to approximate the optimal control law and adopts a self-tuning and
    fuzzy sliding mode compensator to compensate unmodeled dynamics for the active MacPherson suspension
    system. Three experiments are conducted to compare the active MacPherson suspension system with the
    original MacPherson struts through various road profiles on the test-rig. The results show the significant
    improvement for the proposed active MacPherson suspension system in suppressing the displacement and acceleration of the car-body.
