中文摘要: 本项目对连续时间Ito 系统和离散时间乘积噪声系统的谱配置及其H2/H∞设计进行了深入的研究,获得了丰硕的成果,圆满完成了制定的目标: 1.对连续时间Ito系统,引进了区间稳定性和能稳性的定义,并给出了区间稳定性的充分必要条件和区间能稳性的充分条件。 2.对连续时间Ito系统给出了广义D-稳定和广义D-能稳的概念,对D-稳定性给出了易于验证的充分必要条件,对扩散项不含控制的系统,给出了其D-能稳的必要条件。 3.对离散时间乘积噪声系统,我们建立了类似的区间稳定性、能稳性、一般D-稳定和D-能稳性的定义,并给出了相应的判别条件。 4.对于带Markov 跳变的连续和离散时间系统的H2/H∞#25511;制问题,进行了深入的研究, 给出了易于验证的控制器设计算法。

英文摘要: This project has studied extensively the spectral placement and H2/H∞design for continuous-time Ito systems and discrete-time multiplicative noise systems. We have obtained fruitful results and completed our predictive objective successfully: 1. For continuous-time Ito systems, we have defined interval stability and stabilization, a necessary and sufficient condition for interval stability and a sufficient condition for interval stabilization have been presented. 2. For continuous-time Ito systems, we have defined the generalized D-stability and D- stabilization, an easily tested necessary and sufficient condition for D-stability has been obtained. When the diffusion term contains no control input, we have given a necessary condition for D-stabilization. 3.For discrete-time multiplicative noise systems, we have established similar interval stability, interval stabilization, D-stability and D-stabilization together with their test conditions. 4. For both continuous- and discrete-time stochastic Markov jump systems, we have given easily tested conditions for the mixed H2/H∞controller design.
