Abstract

A scanning control system for space optical remote sensors based on the sinusoidal Permanent Magnet Synchronous Motor (PMSM) was explored in this paper. By a control strategy combining composite control with differential negative feedback

the reciprocating motion of a scanning mirror with low velocity and high precision was achieved. The mathematical model of scanning mirror motion was analyzed

and a mathematical model of PMSM under the

d-q

coordinate system was established. By using the

=0 vector control strategy

the simulation model of the control system based on space vector pulse width modulation was built using the MATLAB/SIMULINK

and the current

speed and the position loop were designed. A simulation and an experiment were performed

the results show that the velocity average error in the simulation has optimized from 1.27% to 0.92% and the steady-state mean angular velocity error has arrived 2.06% when the scanning mirror is at a constant speed steady state after combing control. Theoretical analysis and simulation experiments show that the dynamic characteristics of control system can be improved by the proposed control method

and it shows the advantages of short regulation time

small overshooting and quickly accurate dynamic response.
