Interconnection and damping assignment passivity-based control (IDA-PBC) is a technique that regulates the behavior of nonlinear systems by assigning a desired port-controlled Hamiltonian structure. In this paper, based on the original dissipative Hamiltonian realization of a single-machine-infinite-bus power system, we design a controller to re-formulate the interconnection matrix and stabilize the...
Due to the extensively usage of the internal structure during the construction of feedback controller, Hamiltonian function method has gained great success in the performance enhancement control of power systems. In this paper we consider the saturated excitation control of multi-machine multi-load power systems using Hamiltonian function method. First, we propose a general result for the saturated...
Port-controlled Hamiltonian system method is very useful in the performance enhancement control of power systems, of which the key step is to model the power system as a dissipative Hamiltonian system, i.e., to complete the dissipative Hamiltonian realization (DHR). This paper proposes a DHR for multi-machine multi-load power systems based on a novel DHR structure for nonlinear differential algebraic...
The exact feedback linearization of general nonlinear differential algebraic systems (NDAS) is investigated in this paper. First, by taking the algebraic variable as virtual inputs, we introduce a recursion inverse algorithm to construct a right inverse system for NDAS. A state feedback linearization control law is constructed based on the inverse system. As an application of the results got in this...
Using the Hamiltonian function method, we investigate the excitation control of power systems presented by nonlinear differential algebraic equations. First, a novel Hamiltonian realization structure for nonlinear differential algebraic systems is applied to the power system. Then we propose a decentralized nonlinear excitation control scheme and analyze the stability of the closed loop system. This...
