This a three fredom degree robot modeled in simulink which is controled ( 3D position control) by a PID. you set the reference trajectory and the robot controled by the PID follows the trajectory in a good way. In order to run open parametros_luis.m run it ( press f5) and then run the simulink.-This is a three fredom degree robot modeled in simulink which is controled ( 3D position control) by　a PID. you set the reference trajectory　and the robot controled by the PID follows the trajectory in a good way.　In order to run open parametros_luis.m run it ( press f5) and then run the simulink.
