Introduction

The round wood is driven by two fixed rolls and one moving roll of the rotating center to rotate and produce the power of rotary cutting. The center support of the driving roller is relatively fixed with the rotary cutter, and the frequency converter controls the rotary cutter motor to push forward, in this way, the veneer is planed out from the log by the rotary cutter, and the thickness of the veneer is controlled by the gap between the moving roll and the rotary cutter and the driving speed of the rotary cutter motor. Therefore, it is very important to design a frequency conversion control system which can accurately control the moving speed of the rotary cutter to control the thickness of the rotary cutting plate. The basic idea of the system design is: first, establish an accurate mathematical model, then take over the original speed control system to achieve accurate speed control.
