In this chapter, a photovoltaic system integrated into the building is investigated. The studied structure includes also a battery energy storage system. The overall system is connected to a four-wire AC bus, with the possibility to supply single-phase and three-phase loads. Each equipment is interfaced with a dedicated power converter. This chapter examines the technical operation of all structure components and gives a detailed mathematical study of the DC/AC power converter control in case of two modes, namely, grid connected mode and standalone mode. The investigated control is based on resonant controller. The resonant controller parameters tuning, which is based on the generalized stability margin criterion, is detailed in this chapter. To prove the performance of the proposed control algorithm, several simulation tests developed under PSIM software were performed and then validated by experimental results.

The Proportional-resonant controllers (PR) are introduced to fulfil the increased demand for controllers capable to follow or reject periodic signals with superior performance than conventional PID controllers.The main characteristic of these controllers is the very high gain in the frequency of interest, which can lead to stability problems and makes their design and tuning more complex. This paper presents the computation of PR controllers parameters based on the frequency response method, using stability margins and sensitivity functions as indicators of performance and stability for the controlled system. The proposed method is tested using different classes of processes found in typical control problems. Resumo: Os controladores Proporcionais-Ressonantes (PR) vem suprir a demanda por controladores capazes de garantir o seguimento ou a rejeição de sinais periódicos com performance superior aos controladores PID convencionais. A principal característica desses controladoreś e o ganho elevado na frequência de interesse, o que pode levar a problemas de estabilidade e torna complexo seu projeto e sintonia. Este artigo apresenta a síntese de parâmetros para os controladores PR baseada no método da resposta em frequência, utilizando as margens de estabilidade e a função de sensibilidade como indicadores de desempenho e estabilidade do sistema controlado. O método propostoé testado para diferentes classes de processos encontrados em problemas de controle típicos.

“…In order to contribute to the applicability and enlarge the dissemination of resonant controllers, whose parameters are typically tuned considering the knowledge of the plant model, a tuning method of a resonant structure for plants that have an ultimate frequency (that is, whose Nyquist plot crosses the negative real axis) has been proposed in [9]. This method can be implemented experimentally in a straightforward manner, through the same standard relay feedback experiment [10] that is commonly applied to PID controllers.…”

“…This method is based on the modified relay feedback experiment presented in [11], which enables the identification of a previously specified point of the plant's frequency response in a single experiment. Then, similarly to [9], tuning formulas for the PR controller are developed to place this point of the loop frequency response at a specified location in the complex plane, chosen to provide appropriate stability margins. A detailed analysis and validation of the proposed method are performed in a wide variety of plants, which demonstrate its applicability to large amount of plants with different characteristics.…”

This paper proposes a tuning methodology for proportional resonant (PR) controllers by using the design philosophy of the Ziegler-Nichols forced oscillation method. Unlike such related methods that are usual for PID design, and those that have been recently proposed for PR controllers, the method in this paper is not restricted to plants whose Nyquist diagram crosses the negative real axis. It involves a feedback experiment with a relay of adjustable phase, which allows the identification of the most appropriate point of the frequency response for each class of plants. The validation of the proposed method, which includes the identification experiment and specific tuning formulas that provide appropriate stability margins for each class of plants, is performed by means of numerical examples in a large variety of plants, showing its wide applicability.
