Motion control of high rise elevator is a typical multi-objective control and nonlinear control problem. To effectively solve the multi-objective control and nonlinear control problem, an linear matrix inequality(LMI)-based and Takagi-Sugeno(T-S) model-based fuzzy approach is employed. First, the generalized T-S type fuzzy model for the system is contructed, and then system global state controller was carried out via the so-called parallel distributed compensation (PDC) scheme. Second, state feedback robust controller was gained based on LMI method. The simpleness and effectiveness of the controller were showed by the simulation, and the robustness was satisfied for the system. Multiobjective control and nonlinear control problems have been solved effectively.

For a class of uncertain single-input single-output (SISO) nonlinear systems with unknown bound functions and unknown function control gain, a novel approach of direct adaptive fuzzy controller (AFC) without supervisory controller is proposed by Lyapunov synthesis. Based on the direct AFC with projection operator, it is developed a fuzzy approximation error estimator as adaptive compensator, which is used to estimate optimal approximation error (OAE) dynamically and reduce the influence of approximation error on system performance. In closed-loop system analysis, it is not required that the OAE is square-integrable or the OAE supremum is known. It is proved that controlled object being bounded is the sufficient condition of the OAE being bounded. The overall controller guarantees that the closed-loop system is global asymptotically stable in sense that all variables are bounded. The proposed controller is demonstrated to be simple and effective by simulation studies for inverted pendulum system. It achieves favorable performance with smooth controller output, small tracking error and strong robustness.

To solve the seam tracking problem of the welding mobile robot, a new controller based on the dynamics model of the mobile welding robot is designed. Self-turning fuzzy controller is designed to complete coordinately controlling of cross-slider and wheels, and exactly welding seam tracking was realized by use of the controller. To make the tracking more quickly and smoothly, it utilized self-learning and self-adaptive ability of the neural network to deal with the partial uncertainty and the disturbances of the parameters of the robot model, and on-line compensation dynamics coupling. It is proved that the selected control input torques make the system globally asymptotically stable based on the Lyapunov function selected out. Finally, the effectiveness of the controller is demonstrated by simulation results.

Production continuity is an important process characteristic which receives significant attentions in actual refinery process. However, there hasn't been a sufficient and comprehensive expression of production continuity in literatures of refinery scheduling. The core of this paper is to deal with the scheduling optimization problem of refinery operations based on production continuity. The quantitative performance evaluation criterion of production continuity is given, and the scheduling problem is formulated as a generalized disjunctive programming (GDP) model relied on discrete time representation. The model describes production continuity during different scheduling periods using disjunctive normal form and logic proposition as well as proposed heuristics, and optimizes refinery operations by maximizing production profit and continuity performance. The formulation approach is used to address the scheduling of a refinery. Case study shows that the optimal schedule obtained from the proposed model is more feasible and practical, which illustrates the model's efficiency.

Winding molding is a commonly-used molding method for composite fiber materials, in which the fiber winding tension is an important parameter, since the winding tension directly influences the quality of winded products, making winding tension control a key technique in fiber winding. A new type closed-loop tension control system, with PLC as the main controller, the industrial control computer as the upper-host, alternating numeric servo-electromotor and air cylinder as the actuators, equipped with the angle sensor of real time feedback filament tension change is designed. On the basis of study on the swing bar, the mathematical model of the scheme is established. Tension control in the fiber winding process is validated, combined with NC winding machine. Experimental results proved that the principle of the design scheme is right with tension deviation less than 4per, response time about 0.35s and thus well meets the requirements of the system.

It is a research trend to incorporate neural network with genetic algorithm for solving technical and practical problems. As a single genetic algorithm has slow convergent speed and it is easily falling into local optimum, this paper presents a genetic and simulated annealing hybrid algorithm, which searches the neighborhood using chaos variables. And this paper trains a neural network using the single genetic algorithm and the proposed hybrid algorithm respectively. Simulation results show that the hybrid algorithm has more rapid convergent speed and better searching ability to find the global optimum.

The phenomenon of low efficiency and waste is prevalent in public buildings. One of the reasons is the bad habit of people. There is no way to judge the level of waste ever since a long time ago. In order to analyze the level of building energy utilization to implement low energy building, this paper presents a concept of energy efficiency. It divides the energy of building into two parts. One part if effective energy, the other one is ineffective energy. The answer of effective energy divided by total energy is energy validity. Because the effective energy of building terminal is very difficult to measure directly, we can only use existing examination technology to calculate the parameters such as temperature, illumination and sensation to get change rate of time. Then unifying the behavioral characteristics of people, we gain the time of effective energy using. The ratio of both times can represent energy validity indirectly. In order to confirm this method, we have calculated the energy validity by using data of different buildings. The result indicates that the energy validity can reflect the level of artificial energy waste. It would be a quantitative indicator to obtain reasonable energy consumption of building.
