A METHODOLOGY FOR THE INTEGRATED CIRCUIT AND CONTROL DESIGN OF A BUCK BOOST CONVERTER

Frequently, the design of many processes or systems is performed without taking into account its dynamical behaviour. This leads to lost of performance when the process has to operate dynamically, as the design may impose constraints on the physically reachable dynamic. The joint design of equipment and its control system is an integration technique that incorporates control requirements in the process design stage. This paper illustrates the technique with a buck boost converter. The design has been performed including its control system and allows obtaining a system that complies not only with the static performance requirements but with certain previously fixed dynamic characteristics. The parameters of the converter are obtained through mathematical programming, together with the tuning parameters of the controller, in this case an Sliding Model Control strategy, this one being in charge of ensuring that the process responds adequately under a wide range of demands.
