“…Control systems for power systems [14] and specifically for voltage inverters usually use PI control [21], deadbeat control [11], or a combination of them [4], [20] delta modulation, hysteresis control [26], or even more complex multivariable feedback control [8], [16], [17], [27]. Most of the aforementioned control algorithms are performed in the phasor domain and use modulation techniques without optimality guarantees.…”

This paper proposes an online optimal tracking algorithm to provide the desired voltage magnitude and frequency at the load. This eventually will work as a DC/AC inverter that with appropriate switching of semiconductor devices will convert low DC voltage to high AC voltage. An L´C filter is used to reduce the effects caused by switching semiconductor devices. The proposed control scheme ensures a good tracking of an exosystem that provides the desired voltage magnitude and frequency. It builds upon the ideas of approximate dynamic programming (ADP) and uses only partial information of the system and exosystem. A Lyapunov stability proof ensures that the closed-loop system is asympotically stable. Finally, simulations show the effectiveness of the proposed approach.Index Terms-Power systems, voltage source inverter, approximate dynamic programming.

“…2) Deadbeat Controllers: When the choice of the voltage vector is made in order to null the error at the end of the sample period, the predictive controller is often called a deadbeat controller [85], [94], [95], [97]. Among the additional information given to the controller, nonavailable state variables (e.g., flux and speed) can be included.…”

The aim of this paper is to present a review of recently used current control techniques for three-phase voltagesource pulsewidth modulated converters. Various techniques, different in concept, have been described in two main groups: linear and nonlinear. The first includes proportional integral stationary and synchronous) and state feedback controllers, and predictive techniques with constant switching frequency. The second comprises bang-bang (hysteresis, delta modulation) controllers and predictive controllers with on-line optimization. New trends in the current control-neural networks and fuzzy-logicbased controllers-are discussed, as well. Selected oscillograms accompany the presentation in order to illustrate properties of the described controller groups.

“…First, the proportional gain can be chosen equal to that obtained from a conventional proportional plus integral (PI) design, given the specifications in terms of voltage loop bandwidth and phase margin . Second, selecting , the integral gain can be set so as to ensure the same voltage loop bandwidth and phase margin of the conventional PI control, i.e., (10) where is the integral gain of the conventional PI control. Third, parameter is aimed toward the compensation of the delay of the current control loop and typical values are in the range between 2-4, depending on the current control implementation.…”

“…In the attempt to overcome this problem, several high-performance feedback control schemes have been investigated, such as deadbeat control [9], [10], sliding-mode control [11], optimal state feedback [12], and many others [13]. Although these techniques are able to ensure very good results under large-signal disturbances, the total harmonic distortion (THD) on the output voltage due to nonlinear loads can be still quite high, especially in high-power applications.…”

In order to achieve the reduction of voltage distortion in ac power supplies (ACPSs), this paper describes an implementation of synchronous-frame control for selected frequencies in the output voltage. The regulation of the fundamental output voltage, as well as that of some low-order harmonics, is achieved using a synchronous-frame controller for each selected frequency in addition to a conventional control. The conventional part conserves good dynamic performance under load changes, while rotating-frame controllers allow a slow, but very precise compensation of the residual errors within the assumption that the harmonics produced by distorting load are slowly varying. Moreover, motivated by a fixed-point implementation, a set of refinements and modifications of the original scheme is proposed, allowing a reduction of signal processing requirements and a new control algorithm structure less sensitive to quantization and rounding errors. This solution is particularly effective for high-power fully digitally controlled ACPSs, where the voltage loop bandwidth is usually not large enough to provide regulation at harmonic frequencies. The proposed control scheme has been implemented using a fixed-point single-chip digital signal processor (ADMC401 by Analog Devices). Experimental results on a 3-kVA three-phase converter prototype show the effectiveness of the proposed approach.
