Opis:: The article presents an auto-tuning method of state feedback voltage controller for DC-DC power converter. The penalty matrices employed for calculation of controller’s coefficients were obtained by using nature-inspired artificial bee colony (ABC) optimization algorithm. This overcomes the main drawback of state feedback control related to time-consuming trial-and-error tuning procedure. The optimization algorithm takes into account constraints of selected state and control variables of DC-DC power converter. In order to meet all control objectives (i.e., fast voltage response and chattering-free control signal) an appropriate performance index is proposed. Proper selection of state feedback controller (SFC) coefficients is proven by simulation and experimental tests of DC-DC power converter.

Opis:: Power electronics is one of the most important elements of today’s industry. Many of converters applications are being considered as critical for plant production process. Offering enhanced functionality in modern AC drives is a way to gain a competitive advantage in power converters market. One of the values to the customers comes from low cost condition monitoring of critical equipment and from optimized maintenance costs. DC bus is one of the elements of power converters. Although the designers pay a lot of attention when designing DC-link circuit, breakdowns and failures of the DC circuit components can still happen. Unfortunately this means that the whole converter must be shut down in emergency mode to be repaired. Nowadays, monitoring of the bus capacitor is becoming one of the desired features from customer side, as well as from the converter manufacturer. Proposed approach presents a method which assures the online evaluation of the equivalent series resistance (ESR) of a DC-link capacitor. The ESR increase trend is an important indicator of accelerated aging process or incoming failure of the capacitor. The important feature of the proposed condition monitoring method is that it does not require any additional sensors. For estimation purposes already installed sensors and other internal converter’s signals are used. Particularly the method employs the DC-link voltage measurement with the DC-link current reconstruction.
