As the long transmission line, complex mechanism, poor performance of regulation and control and low sensitivity of mechanical let-off, so it can not meets the requirements of stable tension. Therefore, the let-off mechanical was improved. This paper takes let-off system of SAURER400 rapier loom as experimental subject, mathematical modeling to every parts of loom, and takes simulation and comparison. The simulation results show the improvement of mechanical can meet the basic requirements of weaving, and it indicates the works that done former are effective and correct.

We present a new technology for real-time walking of a humanoid robot. A humanoid robot necessitates achieving stabilization for real time walking since it has basic problems such as structural stability. In this paper, a robust control algorithm for stable walking is proposed based the ground reaction forces, which are measured using force sensors during walking, and the environmental conditions are estimated from these situation. From this information the robot selects the proper motion and overcomes ground irregularities effectively. In order to generate the proper angel of the joint. The performance of the proposed algorithm is verified by simulation and experiments for a 20-DOFs humanoid robot.

A gradated cardioresponsive Left Ventricular Assist Device (LVAD) control algorithm was developed in order to improve cardiac reverse remodeling in patients who suffer from late to end-stage heart failure. This algorithm was created to improve physician control of the LVAD as well as improve awareness of the patient's condition. The control algorithm was validated using a mock circulatory system and simulated LVAD.

It is studied the control algorithms of automatic train operation (ATO), which concerns many functions during the train's operation, such as efficiency, punctuality, energy-economizing, stop precision, comfort and so on. In addition, energy-economizing arithmetic uses the control mode which operates according to target speed and makes the best use of coasting, timing arithmetic uses heuristic arithmetic that adjusts target speeds. On the other hand, the operating conditions of the train's being punctual or behind the schedule are all simulated on the computer, and the results are compared with those from practical operation. It is an effective method for further studying of automatic train operation system.

With the development of the intelligent construction in China, the research on the control method of its environment temperature has become an important subject for the related research field. Based on the dynamic analysis of the room temperature and air-condition system, the serial control strategy is presented in this paper, in which the master loop concerns with the control of the room temperature, and the slave loop is the control of the parameter delivering wind. Through the deep analysis of its work performance, it is proved that the serial control strategy is better than the single loop control because it can decrease the dynamic gain of the second interference for the loop of the room temperature. In the end, its control algorithm, whose master loop is PID and slave loop is PI, is investigated, and the good control effects about decreasing the dynamic error and compressing response time are gained by an experiment.

IRMCF343 is designed to achieve low cost and high performance one chip solution for digital PFC and PMSM with sensorless control. This paper introduces the digital PFC control algorithm of the chip in detail, designs a novel, bridgeless PFC topology which has simple current sensing circuit and low EMI, and compares bridge-less PFC and conventional Boost PFC circuits. Experimental results verify that the bridgeless PFC has higher power factor and efficiency comparing with conventional Boost PFC. When the designed bridgeless PFC circuit's power is 1 000 W, the power factor is more than 0.98, the THD is less than 10%, the efficiency is more than 0.97, and the EMI test result is lower than standard.

Accurate power factor definitions are of great importance for industries due to the fact that they affect the billing strategy. They also considerably affect the generation and distribution losses of the power system. At the moment, there are some ambiguities in power definitions to be used for this purpose. In recent years, because of a rapid growth in industry and the use of variable loads such as electrical furnaces and variable speed motors, there is a need for fast compensators that are capable of tracking load changes. One of these facilities is TSC, a capacitor bank that is controlled by static switches (thyristors). In this paper, the performance of these compensators in power factor correction for asymmetrical and variable loads in terms of PF-control capability, system losses and the THD of the input current based on various power factor definitions has been investigated, and a PF definition compatible with a commonly used control algorithm is proposed. Simulations have been carried out in PSCAD/EMTDC software environment.
