The first part of paper describes step by step installation of Switched Reluctance Motor & its drive. A special procedure for installation (Mechanical as well as Electrical) is developed in order to reduce acoustic noise, EMI interference and torque ripple of a motor. A serious electrical interference problem is solved using special designed screened cable. The second part of paper describes dy...

Error factors in the encoded sun sensor (ESS) are analyzed and simulated. Based on the analysis results, an ESS error compensation model containing structural errors and fine-code algorithm errors is established, and the corresponding calibration method for model parameters is proposed. As external parameters, installation deviation between ESS and calibration equipment are introduced to the ES...

Experimental study of multi-path ultrasonic flowmeters measurement accuracy in complex flow fields was carried out in the water flowrate standard facility of National Water Large Flowrate Measurement Station. Several muti-path ultrasonic flowmeters with different path arrangement were studied. The flow disturbances were created by bend, tapered pipe, diverging pipe and butterfly valve. By study...

A new dynamic window algorithm is proposed to solve the problem that optimal trajectory difficult plan and not smooth due dense obstacles in complex workshop path planning task. The sets initial direction angle, then improves evaluation function through angle change factor improve efficiency flexibility of algorithm; fuzzy controller used adjust coefficient function, which adaptability mobile r...

In this paper, power transfer capacity is investigated for systems with a unified power flow controller (UPFC). The combined effects of equipment constraints? system topology and installation locations on the UPFC real power transfer are studied. The P-Q characteristics of UPFC operation under different sets of constraints are determined. The admissible operational ranges of UPFC control output...

density or gravity currents have been always one of the main causes for sedimentation along many of the dam reservoirs. so controlling this phenomenon is very important for increasing useful life of such reservoirs. in this research study the effect of a combination of rough bed and obstacle on the control of sedimentary density current has been investigated. experiments were conducted in a til...

To determine the throughput of automatic gate flushing device, which is part hydraulic water level controller with flexible working bodies, developed by author together Ya.V. Bochkarev, experimental studies were conducted. They carried out method physical modeling model and nature on an installation, installation two models shutter: a) a fixed angle inclination pressure board, b) shutter in for...

In this report, we discuss Tree Music, an interactive computer music installation created using GAIA (Graphical Audio Interface Application), a new open-source interface for controlling the RTcmix synthesis and effects processing engine. Tree Music, commissioned by the University of Virginia Art Museum, used a wireless camera with a wide-angle lens to capture motion and occlusion data from exhi...

Submersible mixer is the core machinery of sewage treatment, which has a profound effect on efficiency and performance submersible mixing system treatment. This paper summarizes scientific research results in recent years from four aspects: structure energy characteristics mixer, numerical simulation calculation method, flow field characteristics, factors affecting characteristics. The existing...

Abstract The velocity obstacle method has extensive research in collision avoidance, which uses circles to represent robots or ships find a collision-free velocity. To better describe the motion characteristics of ships, an improved based on elliptical ship domain is proposed this paper. In previous domains own and target are seldom considered at same time. This paper considers time judges whet...
