This paper investigates the pulse distribution of the three feed motions for the missile-borne radome external contour grinding and meanwhile designs the optimal pulse frequency match method. Firstly, the mathematical analysis model is set up, and the grinding section setting is also obtained. Then the pulse distribution of the X-direction motion, the Y-direction motion and the rotz motion is calculated...
The manual control of anaesthesia is still the dominant practice during surgery. An increasing number of studies have been conducted to explore the possibility of automating this process. The major difficulty in the design of closed-loop control during anaesthesia is the inherent patient variability due to differences in demographic and drug tolerance. These discrepancies are translated into the differences...
To enhance the performance of permanent magnet synchronous motor drive, a sensorless direct torque control (DTC) scheme based on adaptive backstepping control is proposed to control the torque and stator flux linkage, which use five-order permanent magnet synchronous motor (PMSM) dynamic model in the stationary frame with stator currents, rotor flux linkage and rotor speed. In the proposed scheme,...
The study on the bearing capacity and settlement is important to a project. It is useful and concrete to develop a model with some intelligent methods in artificial intelligence area for the prediction of some big structure projects. The validity of the models has been proved by some civil engineering practices. Therefore, the research of bearing capacity and settlement characteristics of rigid pile...
To manage the complexities of vibration reasons, a new method to predict the vibration and analyze the reliability of the turbine rotor is proposed in this paper. Based on analyzing the vibration reasons, the measuring positions of vibration are obtained, and then the rotor will be periodic measured under the normal operation condition to get the test date, namely the amplitude of vibration. Based...
