In this paper, the problem of anticontrol of chaos for a class of stable permanent magnet synchronous motor systems is investigated. The Chen chaotic system is employed to be a reference system. The T-S fuzzy models of the stable permanent magnet synchronous motor system and the Chen chaotic system are introduced firstly. Then, based on the constructed T-S fuzzy models, a fuzzy state feedback controller is imposed on the stable permanent magnet synchronous motor system to track the reference system asymptotically. When the asymptotic tracking is reached, the chaotification of the stable permanent magnet synchronous motor system will be realized.Index Terms-PMSM system, non-smooth-air-gap, chaotifica tion, Chen chaotic system, T-S fuzzy model.978-1-4244-8035-7/10/$26.00

Multi-drug resistance (MDR) is an important element which leads to ineffectiveness of chemotherapeutics. The discovery of histone acetylase's unusual activities in tumor cells provides a new area for the cure of cancer. And histone deacetylases inhibitor (HDACi) is used as a new agent in clinical therapy. New histone deacetylases inhibitors have been synthesized. All the products have been characterized by 1 H-NMR and MS. The activities in vitro effects on the title compounds were examined. From the biological activity results, we found that three compounds showed good inhibitory potency against HDACs and anti-proliferate activities to inhibit human colonic cancer cells growth.Introduction.
