Abstract: This paper is concerns with the study of model predictive control of continuous stirred-tank reactor (CSTR). Firstly, a nonlinear mechanical model is established for a typical CSTR. Based on mass balance and energy balance, a set of ordinary differential equations are derived. Then, the model is linearized at steady-state point to obtain state space model, which is used in model predictive control (MPC). Finally, MPC strategy is applied, controller parameters and process constrains are discussed.

Abstract: This paper introduced how to use MATLAB to draw frequency histogram of reliability data distribution, estimate parameters and check up hypotheses, and realize automatic analysis of reliability data to ensure timely and precisely finishing data analysis, shorten the cycle of data disposal.

Abstract: In order to solve the problem of The Enterprise Stratagem Diagnostic ,the system based on Agent by investigation is proposed. This paper presents the Aglet which is used to develop Agent. It uses diversified mutual mechanism to integrative analysis, studying and implement on logical stratagem diagnostic. The paper concretely declares the Master-Slave design pattern which satisfies the system and the Itinerary which is the intelligent rout arithmetic. The Master-Slave design pattern which is favorable of system development advances the repetition of code. The Itinerary arithmetic promotes the security of system and implements the intelligent of Aglet.

Abstract: A three-dimensional grip force sensor with new elastomer structure is developed. By using the simulation of finite element method, the relationship between force and strain is analyzed, the characteristic values of the key points is extracted and the coupling performance between dimensions of grip force sensor is analyzed. The static calibration system is set up and the decoupling matrix of grip force sensor is obtained. Experimental results shows that the new type sensor can eliminate the coupling among the three dimensions effectively.

Abstract: by studying steelmaking-casting-rolling production process, a mathematical model of integrated batch planning is established innovatively to minimize processing costs of whole line and computed by an intelligent optimization ant algorithm. On the premise of utilizing and coordinating capacity of steelmaking and rolling, the mathematical model of integrated batch planning can create integrated batch planning to combine steelmaking-casting-rolling closely according to each process constraint conditions and optimization objective. Furthermore, another mathematical model of job scheduling based on heat process model is proposed to not only guarantee the logistics balance between continuous casting and hot rolling, but also acquire the highest ratio of DHCR and lowest energy consumption.

Abstract: In order to make more precise monitoring and automation of roadway, the paper presents a method based on computer vision. The first step is to get the edge information of marked points though image preprocessing, then calculate the planar coordinates of marked points and decode. The next is to set up the camera model to solve all the initial parameter and distortion coefficient of camera and initial marked points. Finally, the bundle-adjustment can refine all the camera parameter and the three-dimensional of marked points. Experience shows the method can achieve accurate three-dimensional information and make efficient adjustment about roadway deformation.
