The research of joint controller of strawberry picking robot <br /> based on DSP<br />
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 3
Abstract
This paper takes the permanent magnetic synchronous motor as motivity，adopts the position servo control strategy of three closed-loop control and adopts the vector control strategy of zero straight axis electric current. Manufacturing motion control board with DSP for processor，using ACPM750E as the motor power driver and amplifier，programming the software of the control system. Experimental results show that the controlling error of the controller based on DSP is in the range of 0.5%.
