Abstract: The robot's motion control system is the core technology of intelligent robot. In this paper based on immune genetic algorithm, we improve the intelligent robot control system, and design the intelligent robot action output system with adjustable ratio combined with the PID algorithm. The system has the adaptive adjustment function, by adjusting the proportional coefficient P, which can reduce the output error of the system, improve the adaptability of the system and accelerate the speed of motion control. Finally, we use Siemens S7-200 series products to simulate the action output, and obtain the output time and residual of action under different proportional coefficient P by simulation. It provides the technical reference for the research on control algorithm of intelligent robot.

Abstract: Blood pressure is one of the most important indexes for human beings health. This paper presents an optimized algorithm to measure arterial blood pressure based on oscillometric technique. The bilateral filter and Gaussian-fitting method are respectively expressed to apply in noise eliminating, oscillation pulse extracting and curve fitting. The systolic pressure and diastolic pressure are determined by combination of proportional coefficient method, maximum slope method and curvature method. Moreover, a judgment for arrhythmias is employed in heart rate calculation. Experimental results have proved the precision and accuracy of the algorithm.

Abstract: Grinding temperature is the main factor to limit the improvement of grinding efficiency. The main reason of grinding temperature rise is amount of heat transfer into the workpiece in grinding process. How to determine the proportion ratio, which heat transfers into the workpiece, is the main research issue to the precise machining scholars. In this paper, the heat resistance model is used to analyze the proportional coefficient about how much heat transfer into the grinding wheel, and the factors which to influence this coefficient are discussed. The moving heat source method is used to calculate the temperature field caused by single grain heat source, and the heat integral method is used to calculate the heat contains by the grinding chip, and then the heat proportional coefficients transferring into the chip and workpiece are determined respectively.
