چکیده انگلیسی مقاله:
Abstract - A time-domain design method for the digital controller of pulsewidth modulation dcdc converters was developed. The proposed approach is based on the fact that the closed-loop response of a digitally controlled system is largely determined by the ?rst few samples of the compensator. This concept is used to ?t a digital PID template to the desired response. The proposed controller design method is carried out in the time domain and, thus, bypasses errors related to the transformation from the continuous to discrete domain and to discretization. The method was tested by simulations and experimentally. Digital PID controllers for experimental buck- and boost-type converters were designed according to the proposed method and implemented on a TMS320LF2407 DSP core. The measured closed-loop attributes were found to be in good agreement with the design goals. The study was further expanded to investigate the possible realistic closed-loop performance that can be obtained from a system that is controlled by a PID template controller, as well as the stability boundaries of the proposed time-domain controller design approach. The results of the study delineate a normalized map of deviation from the target closed-loop performance goals possible for PID control of switchmode converters and the areas in which the use of this control law is feasible.
