Title Dual motor control system model simulation
based on macro/micro drive
Abstract
With the rapid development of modern science and technology, servo system on the control precision and response speed and robustness requirements continue to improve, two-stage drive servo system arises at the historic moment, has been well developed and widely applied. To make use of the advantage of the performance of two sets of motor system control, so that both can drive high power load, but also can realize the precise adjustment of key components, this paper was based on the above reasons, is committed to study the macro micro bipolar drive control method, set up from the servo system macro/micro driven model to the optimization of PID control method of simulation, the accuracy of the system regulation. First of all, the design ofthe system overall plan, operation mode of two level platform of their own and connection control strategy. To establish the mathematical model of PMSM vector control, on the basis of vector control principle, coarse and fine channel platform three loop structure simulation model is built using Matlab /Simulink tools, combined with general structure design of the whole servo system simulation model is built. Secondly, we design the two platform position loop PID controller and the control algorithm and the coordinated control module was improved at the same time improve the strategy of connection between the two platform. Finally, according to the different parameters of the PID controller of the impact response of the system to complete the matlab simulation.
