In this paper, as a typical lewis acid, anhydrous aluminum (AlCl_3) was used as the catalyst to get PP/PS blends compatibilized by in-situ Fridel-Crafts alkylation. The effects on PP and PS components of AlCl_3 were investigated first, mainly by rheology, including steady rheology method and dynamic rheology method. Then the in-situ reactions in PP/PS alloys under different conditions were executed and studied in detail by selective Soxhlet solvent extraction. And at the same time, the evolutions of phase structures of PP/PS and the resulted PP/PS/AlCl_3 alloys were investigated by SEM and SALS. The steady and dynamic rheological behaviors of in-situ compatibilized PP/PS alloys were obtained systematically.

The contents of this dissertation are involved in studies on quasi steady-state condition of a slow speed-varying rotor system, gain-scheduling control of a quasi steady-state rotor active balancing system, adaptive control of active balancing for a fast speed-varying rotor with actuator time delay and adaptive control of active balancing for a fast speed-varying rotor with actuator saturation.

Under the premise of a rotor system satisfying the quasi steady-state condition, the influencing coefficient method based on the steady-state rotor balancing is extended to single-plane or multiple-plane gain-scheduling control of a rotor with slowly varying speed and all factors affecting the stability of a gain-scheduling control are analyzed. Numerical simulations verify that the gain scheduling control can effectively suppress imbalance-induced vibration of a rotor with slowly varying speed.
