The traditional artificial potential field method is suitable for stationary environment. In practical application, mobile robot is in a dynamic environment where the target and the obstacles are moving. For the dynamic environment, the relative position and velocity of the moving target with respect to the mobile robot and the mobile robot with respect to the moving obstacles are taken into account...
For the existence of the potential safety risk, it is necessary to reveal the distribution of these hidden defects in the seawall body. Based on the analysis of seawall engineering and foundation characteristics, ground penetrating radar (GPR) has been used to identify the hidden defects and quality status of loosening weak layers in the seawall body (clay). The detection results are in good agreement...
Seawall is an important public facility which can protect areas of human habitation from the destructive aspects of tides or waves. Maintenance and monitoring of seawall structures plays an essential role in public safety and prevention of flooding of areas behind the seawall. The presence of hollow area beneath the concrete slab of riverside slope can result in the settlement and distortion of face...
Beer fermentation process has the characteristics of nonlinear, time varvine and pure lae. Since tradition PID control and fuzzv PID control are difficult to satisfy the control reauirements, an improved variable universe fuzzv PID control method is proposed. The variable universe fuzzv controller is improved bv adapting scale partition method. PID control, fuzzv PID control and imnroved variable...
Aiming at solving the problem of the nonlinear strong coupling between temperature and humidity in the greenhouse, this paper presents feedback feed-forward linearization and decoupling algorithm for climate control of greenhouses. Using this algorithm, the nonlinear multiple-input multiple-output (MIMO) system is transformed into two independent single-input single-output (SISO) first-order linear...
Intelligent control has been greatly developed and theoretically researched, but it is usually limited to the off-line simulation research. In order to put advanced control algorithms into practice, using a reliable OPC (OLE for Process Control) technology to connect the field process and control equipment, and to realize the data reading in real time, the specific implementations way to achieve real-time...
The fuzzy PID controller can adapt to the change of the controlled object, so as to realizing the control requirement of chlorine flow in the chloroacetic acid reaction kettle. Theoretical analysis and MATLAB simulation results show that fuzzy self-adaptive PID control has better control performance than conventional PID control.
In addition to the traditional analog filter circuit, an intelligent filter chip MAX260 that can track signals with a certain frequency, and keep their amplitude and phase constant but attenuate signals with other frequencies as the microchip controller part's filter is added after the pre-processing circuit. Combining MAX260 and digital filtering arithmetic, the anti-disturbance of the conditioning...
The potential failure zone in a seawall is a hidden danger that requires exact and immediate detection. Of all the different geophysical exploration methods, ground penetrating radar (GPR) has proven to be the most effective, non-destructive, highly efficiency detection method. It has been successfully used to investigate the structure and condition of many seawalls in Eastern China. In this study,...
When painting with the high speed electrostatic rotation bell, on the surface of object being painted, many kinds of deposition models will be formed by the atomized painting particles. Based on the analysis of those deposition models, the β-distributed deposition model is studied adequately, and the coating thickness deposition function, which includes the paint flow bottom radius R, adjustment coefficient...
For the purpose of synchronization of three independent DC motors which were used to drive the supporting poles of a table-lift, a “master-servant” structured control scheme is introduced. By taking the master pole's output as reference signal and the servant pole's output as feedback signal, servant poles become the followers of the master pole. Hall sensors are employed to transmit the rotations...
As an important part of realizing higher education popularization, all sectors of society attach great importance to the development of independent colleges. From its creation and development, this paper gives depth analysis on the dominant, gray and implicit characteristics of the independent College, indicates the development trends of independent colleges and presents its developing measures in...
As the enrollment expansion of Independent College, the demand for teachers has increased dramatically. Taking the analysis of the characters of the students, cultivation purpose and the teaching faculty construction as the point of departure, this paper focuses on analyzing the problem existed in the teaching team construction in Independent College, and some improvement measures are proposed for...
According to the characteristics of control special and the society's demand, the reform idea is proposed based on the combination of computer and the control class curriculum group. Based on the reform principle, it carries on the exploration and practice in the teaching goal, the course content, the educational model, the practice teaching and so on. From the practice result it shows that it not...
According to the characters of relatively weak cultural foundation though the overall quality relatively high of independent college students, the “Automatic Control Theory” teaching reform ideas and methods are proposed combining with long-term teaching experience and the application of network and information technology. The curriculum reform includes many aspects such as teaching content, teaching...
Some problems of traditional experimental teaching in colleges are analyzed in this paper, then a three layers experimental system is put forward based on reforming and innovating the mode of talent training as fundamentality and development and reconstruction of new experimental equipment and experimental platform. In practice, focusing on the connection between knowledge, creating a new context,...
Recently, intelligent video surveillance system with multiple cameras is a research hotspot due to its wide application. This system has many advantages on improving the surveillance performance and extending surveillance functions. However, taking multi-camera resources and video data into account, many problems also need to explore and research. The paper designs a system that fuses tracking information...
Based on the structure characteristics and operating principle of the continuous 3R oblique axis non-spherical wrist, a full parameter error identification model of this wrist was setup, and calibration experiment on this wrist were accomplished with a Xi type 3D laser tracking instrument made by FARO Company in American. After calibrating and compensating, the single axle positioning accuracy of...
Coagulant dosing process is an important part in water treatment plan, it directly affects the water quality and operating costs of production. It is very difficult to set up its mathematical model accurately basing on its reactive mechanism at present. Factors that affect the coagulation effect are analyzed in this paper, then a BP neural network prediction model of coagulant dosage is established...
Based on the study of MATLAB/RTW function,a hardware-in the loop experiment simulation system is designed.
