Simulation of Control Systems for a Mobile Robot Platform


Dr. Ramin Shamshiri


Control design for Field Survey Mobile Robot using lead-lag compensation, PID and Fuzzy Logic

% m-code number two

% Design and Simulation of Control Systems for a Field Survey Mobile Robot Platform using lead-lag compensation, PID and Fuzzy Logic
% To customize this code you need to:
% 1- Change the values of DC motor constants 
% 2- Change the zeros of lead-lag compensation
% 3- Change the gains of PID controller
% 4- Change the rules of Fuzzy logic controller
