A mode switching based transient ride‐through phase‐locked loop

Mode Switching

In many control applications, a speciic set of output tracking controllers of satisfactory performance have already been designed and must be used. When such a collection of control modes is available, an important problem is to be able to accomplish a variety of high level tasks by appropriately switching between the low-level control modes. In this paper, we deene a concept of control modes, ...

Sliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency

In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...

Fast Mode Switching for a Thrust Vectored

Aircraft operate in diierent modes during ight, corresponding to diierent ight conditions and control schemes. We use diierential atness of an approximate model of the pitch dynamics of a thrust vectored aircraft to achieve fast switching between those modes. We investigate some methods to compensate for the perturbations to atness. Simulations and experimental data are provided to validate the...

State-Based Mode Switching with Applications to Mixed-Criticality Systems

We present a new graph-based real-time task model that can specify complex job arrival patterns and global statebased mode switching. The mode switching is of a mixedcriticality style, enabling immediate changes to the parameters of active jobs upon mode switches. The resulting task model therefore generalizes previously proposed task graph models as well as mixed-criticality (sporadic) task mo...
