چکیده

We consider distributed parameter systems where the underlying dynamics are spatially invariant, and where the controls and measurements are spatially distributed. These systems arise in many applications such as the control of platoons, smart structures, or distributed ow control through the uid boundary. For optimal control problems involving quadratic criteria such as LQR, H2 and H1, it is shown how to reduce the optimization to a family of problems over spatial frequency. We also show that optimal controllers have an inherent degree of decentralization, which leads to a practical distributed architecture. Under a more general class of performance criteria, a general result is given showing that optimal controllers inherit the spatial invariance structure of the plant.

The Structure of Optimal Controllers of Spatially-Invariant Distributed Parameter Systems

We consider distributed parameter systems where the underlying dynamics are spatially invariant, and where the controls and measurements are spatially distributed. These systems arise in many applications such as the control of platoons, ow control with large arrays of sensors/actuators such as in Micro Electro Mechanical Systems, and systems described by partial diierential equations with cons...

Distributed control of spatially invariant systems

We consider distributed parameter systems where the underlying dynamics are spatially invariant, and where the controls and measurements are spatially distributed. These systems arise in many applications such as the control of vehicular platoons, flow control, microelectromechanical systems (MEMS), smart structures, and systems described by partial differential equations with constant coeffici...

Distributed multi-agent Load Frequency Control for a Large-scale Power System Optimized by Grey Wolf Optimizer

This paper aims to design an optimal distributed multi-agent controller for load frequency control and optimal power flow purposes. The controller parameters are optimized using Grey Wolf Optimization (GWO) algorithm. The designed optimal distributed controller is employed for load frequency control in the IEEE 30-bus test system with six generators. The controller of each generator is consider...

Modeling and Observer Design for an Array of Electrostatically Actuated Microcantilevers

In this paper we present a mathematical model for the dynamics of an array of capacitively actuated microcantilevers. We propose a system where the current measured at each cantilever is used as the sensing signal of the cantilever state through an observer. We show that such an array is a spatially invariant system with distributed control and sensing. For the common case of periodically excit...

Reduction and Equivalence of Nonlinear Distributed Symmetric Control Systems

This paper considers the ‘reduction’ problem for large-scale distributed control systems. In particular, we consider control-theoretic concepts for control systems containing multiple instances of identical controllers or components where the overall system is invariant with respect to interchanging these identical components. The main results are invariance of controllability, motion planning ...
