Simulation systems with hardware-in-loop are composed by three-Axis virtual flight motion simulator
simulation computer
load torque simulator
and visual simulation systems. Three-Axis Virtual Flight Motion Simulator are used to simulate the attitude of missile in simulation system with hardware-in-loop
so its performance influenced the result of simulation directly. This paper mainly analyzed the factors which influenced the performance of a three-Axis virtual flight motion simulator which we are used now in the lab
then analyzed the entire simulation system's error caused by these factors through numerical simulation method. By analysis we can see that bandwidth is the main factor influenced the precision of simulation systems with hardware-in-loop
mechanical device installation error and measurement error may also cause some errors of the systems at the same time.

The azimuth bearing schemes in typical large Alt-azimuth telescopes
especially the 3.5-m APO telescope and the 4.1-m SOAR telescope were analyzed. A scheme of high-angular contacted thrust ball bearing integrated with a radial ball bearing was put forward. According to the Hertz contact theory
the corresponding parameters were designed for engineering application. The static performance parameters
within the range of 60 85 original contact angle were calculated. Compared with the traditional plane thrust ball bearing
the results shows that the high-angular (80) contact thrust ball bearing has more benefits at bearing strength and rigidity for large telescope. The 1500mm diameter prototyping bearing shows good performance
including the axial jitter is 0.009mm
the radial jitter is 0.006mm
the maximum starting torque without load is 30N·m
and the load capacity is more than 30t
which offers advanced technique path for the buildup of the high precision azimuth shafting and the whole telescope system. 2010 Copyright SPIE - The International Society for Optical Engineering.

This paper dealed with position control problems of a DC motor servo system that had nonlinear friction and was subject to parametric uncertainties
external disturbances
etc. In order to overcame those unfavourable factors mentioned above
a model reference adaptive control method was proposed to regulate the important and main speed loop in the positioning system which was designed with three closed control loop
where a compensatory measure was given so as to counterbalance the friction torque disturbances. In addition
the other two close loops were built in adjusting the position and the current of the servo system respectively that aimed to achieve the fast and precise positioning and increase dynamic stiffness against load disturbances. Experimental results illustrate satisfactory performances in steady state error
load capability
high rapidity and so on. 2010 IEEE.
