Design and implementation of a simplified control platform for the feedback of a CNC plotter
Abstract
In this paper the design and implementation of a simplified control platform for the feedback control of a CNC plotter is carried out; A PID controller is programmed for servo motor control which is based on block programming in Simulink-Matlab. The feedback is done through the Atmel 2560 microcontroller development card programmed to acquire the encoder data of a UNITEC servomotor. Experimental validation shows that the integration of the different sampling modules in a block programmed in Simulink-Matlab, simplifies the electronic design of signal conversion, by software implementing many signal conversion routines, which previously was not possible directly , making it easier for researchers to develop and test new control algorithms on the platform directly and in real time.
