Achievement of Bevalac Rapid Mode Switching

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, ...

Bidirectional Control of Generalized Epilepsy Networks via Rapid Real-Time Switching of Firing Mode

Thalamic relay neurons have well-characterized dual firing modes: bursting and tonic spiking. Studies in brain slices have led to a model in which rhythmic synchronized spiking (phasic firing) in a population of relay neurons leads to hyper-synchronous oscillatory cortico-thalamo-cortical rhythms that result in absence seizures. This model suggests that blocking thalamocortical phasic firing wo...

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...

Hierarchical modeling of mode-switching systems

This paper introduces a set of input-output blocks to build intuitive models of dynamic systems with mode switching due to changes in operating conditions, sensor failure, model reconfiguration, and model-order reduction. These blocks make it possible to construct hierarchical component models of mode-switching systems. An application to an automotive steer-by-wire example and Simulink simulati...
