Special Issue Information

Dear Colleagues,

As you are well aware, a self-healing system automatically detects, diagnoses, and repairs localized software and hardware problems. For a fault-tolerant system, fault diagnosis is the first step once a fault occurs. An accurate and timely detection and protection can prevent fault propagations and catastrophic consequences. Fault-tolerant operation, consisting of fault isolation and fault reconfiguration, is the next countermeasure, which is always based on hardware redundancy design and corresponding fault-tolerant control.

Today, power converters are essential for the energy transition toward a system based on renewable electric energy generation, electric power storage, and the electrification and integration of new vehicles. Therefore, the future will be focused on the application of self-healing and fault tolerance technologies for smart converters.

The main goal of this Special Issue is to publish new scientific knowledge relevant but not limited to the following topics:

  • Self-healing control of power converters;
  • Fault detection techniques in power converters;
  • Fault diagnosis techniques in power converters;
  • Fault tolerance power converters;
  • Prognostics in power converters;
  • Smart converters;
  • Techniques to improve reliability of power converters

In this article, a novel systematic approach is proposed for a partial sliding mode controller (SMC) design and tuning in non-minimum phase switch-mode power supplies (SMPS). To achieve a more simplified controller in comparison with the conventional SMCs, the partial SMC (PSMC) is introduced in this article, which just requires a part of the sliding surface for controller formulation. The accuracy of the developed PSMC is proved mathematically within the entire range of operation. Since the control parameters of the PSMC are not selected by trial and error, it can maintain the stability and robustness of the closed-loop system in a broad operational range. In this regard, and to develop a systematic approach for robust control of SMPS, a constant frequency equivalent SMC is designed using the converter nominal parameters. Then, the extracted controller is combined with an adaptive component to ensure asymptotical stability against load and line changes. Considering the Lyapunov stability criteria for nonlinear systems, it is proved that the presented SPMC can be used for output voltage regulation in both discontinuous and continuous operating modes with zero steady state error. To avoid the trial and error method during the controller tuning and parameters selection, the system characteristic equation is extracted using the Jacobian approach. Considering the roots of the characteristic equation and the stable range of the closed-loop system, the controller parameters are tuned. Furthermore, in addition to simulation, the developed approach is evaluated practically using the TMS3220F2810 digital signal processor. It is shown that the dynamic response of the proposed approach is faster than the standard double-loop SMC during load and line changes. Additionally, it is seen that the developed controller is robust against model changes in both continuous and discontinuous operations. Full article
