Chapter 5 deals with the solvable theorem of adaptive inverse optimal control problems for a class of stochastic nonlinear systems driven by Wiener noises of unknown covariance. The systems are depicted by It〓 stochastic differential equations. By using an adaptive backstepping algorithm and stochastic control Lyapunov functions, the designing procedure of control laws of global asymptotic stability in probability and adaptive inverse optimal stabilization in probability are presented systematically. Adaptive control laws and parameter update laws can be obtained at the same time by this design scheme.

On the basis of stability analysis, the author takes the K27+825 slope from the type of slope which has lest stability as an example. According to its basic feature, the design ueses the choosed best reinforce and control scheme: lattice beam, anchor wire, grouting and abstraction of water. In the course of design, the author takes into account not only reasonable optimize of whole control plan but also local measure such as whether the unstable block will shear from vnlnerable sections when control plan is laid out concretely, in order to reach the goal of reasonable design and effective control.
