Design of PID controller based on information collecting robot in agricultural fields

Abstract

Field information collecting is an important part in precision agriculture. With the mechanical structure of a new kind robot which is used for field information collecting, the main controller of the robot and the physical circuit board are developed The position PID algorithm is simulated by Matlab/Simulink and PID parameters are tuned by the critical proportioning method The single chip C8051F340 is selected to control two DC motors, which can drive the robot. Simulation and circuit experiment show that the algorithm is effective and this controller can work in high reliability and stability.
