摘要:

AbstractThe problem of non‐linear field voltage controller synthesis for a synchronous generator is considered. The theory of feedback linearization of non‐linear systems is applied and the existence of a linearizing feedback controller for the improved reduced‐order three‐dimensional model of a generator is proved. Simulation results for the proposed non‐linear controller, which includes a non‐linear observer and two systems based on an automatic voltage regulator and a power system stabilizer, ar

摘要:

AbstractThe paper presents a computer‐aided procedure for multipurpose controller design which in multivariable (linearized) stochastic systems simultaneously ensures (1) complete dynamic decoupling of control loops, (2) arbitrary closed‐loop pole placement and internal stability of the control system, (3) steady state output rejection of non‐zero mean values of disturbances as well as zero steady state regulation and/or tracking errors, (4) reduction of amplitude modulation of the control signals and (5) optimal steady state estimation of the plant's state and output vectors. The polynomial matrix approach in the frequencys‐domain is used to solve the stochastic control problem. Numerical results and simulations for a simplified version of a ship‐positioning control system design are presented to illustrate characteristics of th

摘要:

AbstractA class of discrete time feedforward tracking controllers is presented for linear multivariable plants subjected to time‐varying exogenous inputs with known models. The controller design is based on linear quadratic optimization techniques and the augmented system approach. The optimal controllers use state feedback for regulation purposes. For the tracking objective the future set‐points along the reference trajectory vector are used. Necessary and sufficient conditions for the existence of an optimal feedforward solution are presented in terms of the relationships between the eigenvalues of the closed‐loop system and those of the trajectory models. For illustration a numerical example is included which is based on a dual‐stage positioning carriage modelled as a linear multivariabl
