The crustacean stomatogastric ganglion (STG) receives descending neuromodulatory inputs from three anterior ganglia, the paired commissural ganglia (CoGs) and the single esophageal ganglion (OG). In this paper we provide the first detailed and quantitative analyses of the short- and long-term effects of removal of these descending inputs (decentralization) on the pyloric rhythm of the STG. Thir...

Load Frequency Control (LFC) has received considerable attention during last decades. This paper proposes a new method for designing decentralized interaction estimators for interconnected large-scale systems and utilizes it to multi-area power systems. For each local area, a local estimator is designed to estimate the interactions of this area using only the local output measurements. In fact,...

We augment existing generator-side primary frequency control with load-side control that are local, ubiquitous, and continuous. The mechanisms on both the generator and the load sides are decentralized in that their control decisions are functions of locally measurable frequency deviations. These local algorithms interact over the network through nonlinear power flows. We design the local frequ...

Air conditioners have great potential to participate in power system frequency control. This paper proposes a control strategy to facilitate the active participation of air conditioners. For each air conditioner, a decentralized control law is designed to adjust its temperature set point in response to the system frequency deviation. The decentralized control law accounts for the user’s thermal...

This work extends the current results of SISO (single-input-single-output) case H-infinity PID Controller synthesis in finite frequency domain to the subject of multivariable decentralized control. Sufficient conditions for the existence of such a decentralized PID controller are derived in terms of linear matrix inequalities (LMIs). A numerical example is given that establishes the efficacy of...

This paper deals with the exponential stability analysis of decentralized, sampled-data, Linear Time Invariant (LTI) control systems asynchronous sensors and actuators. We consider case where each controller in decentralized setting has its own sampling actuation frequency, which translates to asynchrony between Additionally, may be induced by delays instants update as relevant a networked cont...

A new approach to distributed synchronization (frequency alignment) for the coordination of nodes in open loop coherent antenna arrays enable beamforming is presented. This makes use concept consensus optimization among without requiring centralized control. Decentralized frequency can be achieved through iterative exchange nodes. We derive a model signal received from array and analyze effects...
