Design And Implementation Of Micro-positioning FSM Control System Based On Voice Coil Motor

As the top technology,fast steering mirror(FSM)plays an increasingly important role in the domain of space and communication science.We mainly design and research the general FSM in this art icle.What drives the FSM and its relevant mechanical interaction should be considered in a co mplete structural design.Some vital part of it need to be attached more importance to,generally speaking,only in a professional software can we obtain a perfect one.Based on that structural design and to obtain the contro l system we desire,we study the FSM from whole to part to extract the minimum funct ioning model including only one Voice Coil Motor(VCM)which serves as the basic gear of the whole system and the corresponding coupling effect fro m other.And then,establish the dual closed-loop control system according to it.We found PID controller is easy and convenient to use in our system model.But,there exists many disadvantage in it.For example,it's stability tends to be destroyed by external disturbance;A set of parameter is constrained to only one controller,not suitable to others.So,we need self-adapted fract ional PID controller with it's strong robustness applicable for any occasion.After simulation,we verify the algorithms in the comprehensive FPGA&DSP driver circuit board designed totally by ourselves.We simulate the two main CPU in software CCS and Quartus II respectively for their main simulation statistics.And meanwhile,we can track the position curve in the upper computer software incidental by PD-B0409 A driver software package.By comparing the MATLAB simulation results and the positioning curve,we could draw a conclude whether the algorithm is correct and feasible.Our efforts will be helpful for further research and deeper exploration in the future.
