Consequently the NN adaptive unit is added into the control loop according to the NN on-line approximate property. Lastly the chapter combines the proposed shortest path-planning method and the adaptive tracking method in order to stabilize the NWMR about a posture through the shortest path. Many simulations are carried out on MATLAB and the simulation results are very feasible and reasonable. Chapter 5 proposes a new localization method for the WMR running on inclined planes based on fusion of clinometric and an odometric data by Kalman filter.

This work contributed essentially to optimal planning of refinery management. A strategy for solving the decision problem of short—term refinery planning is proposed, that is, to obtain the real time information of unit operations and environmental conditions by means of computer simulation, to dynamically configurate and modify the decision model depending on both simulation and expert reasoning, to make decision analysis and short—term production plan with the aid of expert simulation system. In this paper, a new approach cellad ESDSS was proposed by integrating DSS and expert simulation system . As a case study of ESDSS, a so called RESDSS was constructed, which is composed of seven subsystems, namely: data base subsystem, model base subsystem, method base subsystem, knowledge base subsystem, experiment base subsystem, human computer interaction subsystem, and expert simulation executing subsystem. The main results and contributions of this work are as follows:(1) A novel approach of DSS named ESDSS was proposed, which integrates DSS and ESS.
