Modeling and Measuring Friction of the Leighton 10 m Telescope
文献摘要:
Estimating and identifying friction are important aspects of simulating a mechanical drive system.Accurate friction modeling helps to improve a telescope's performance.However,the friction conditions inside are complex and hard to measure.We did simulations with mathematical transfer functions for the Leighton 10 m Telescope and employed a polyline model to identify sources of friction.We made a two-stage model for the Leighton 10 m Telescope.Based on measurements of the motor's currents and speeds,we constructed a curve containing the friction information of the transmission elements.We simulated the system using a step function input under many combinations of friction parameters.By comparing simulation results with the measured ones,we determined the various friction components.This model accurately reproduced the telescope performance including the nonlinearities.
