“…As the future works, the proposed voltage estimator can be used in some other applications such as the predictive torque control (PTC) of induction motors, predictive control system of active front converters, predictive control system of matrix converters etc. Furthermore, the proposed voltage estimator can be developed by using of advanced numerical solution for the nonlinear equation in (28) and finding the solution with lower computational burden.…”

“…However, for calculating the PCC voltage at each sampling period, by using any mathematical tool, equation (28) must be solved to compute Vc and φL. Then, after calculating the phase and the voltage at the PCC, the components of the instantaneous voltage in the αβ frame can be calculated from (30).…”

In this paper, two observers for the model predictive control system of the active load balancer (ALB), are proposed. An unbalanced single-phase load in the distributed power system causes significant difficulties. An active load balancer is an efficient approach to tackle these issues. Model predictive control is one of the centralized proper control system for a power electronic converter. The main drawback of this control system is the use of numerous voltage and current sensors. Therefore, using of observers instead of sensors makes the implementation of the model predictive control system more cost effective. These two observers, estimate the load current and PCC voltage, fast and accurate as possible. This paper presents load current observer based on furrier series and voltage observer based on nonlinear newton-raphson method. The experimental results obtained from a 4 kW prototype ALB validate the theoretical analysis. The experimental results reveal that the proposed observers can achieve high accuracy and low costs as well as a high-quality grid side current.
