The Design and Implementation of Multiple Processors in Control of Multiple High Power DC Motors

Small microcontrollers are popular and easy to use in all kinds of applications. On the other hand, they are also limited in their capacity of inputs/outputs (I/Os), internal peripherals, and external interfacing. In order to extend the capabilities of pre-developed modules, the use of these small microcontrollers must be linked as individual modules through a central control format to accommodate the special needs of a complex project. A serial link between all the modules that uses well defined protocols is essential to the success of project implementation in an efficient and economical way. Using microprocessor/microcontroller in various control applications is not only one of the major topics in Engineering Technology curricula, but also of interest in industry applications. The control of multiple high power DC motors in the range of 10 Amps or above with multiple small microcontrollers poses an interesting and challenging task in design. The implementation and test of the design is also demanding. The solutions, to serially linked multiple microcontroller modules and their controls of high power DC motors, are the focuses of this articl
