摘要:

This paper contains a review of literature and a state space- analysis relevant to the determination of errors in the state vector caused by the introduction amplitude of quantization into a feedback control loop. Furthermore, computational results are presented which show the order of magnitude of these errors and relate the quantization interval to the finite word length of the digital machine, in a hybrid computer simulation of a simple control loop.

摘要:

The evaluation of signal dependent sampling in discrete-continuous feedback systems is extended to include sampling interval criteria with nonlinear integrands. Examples are investigated for a general second-order plant with such integrands as the squares of error, output and a Euclidean norm respectively, and furthermore, performance surfaces in an object function-parameter space have been computed to demonstrate system behaviour.

摘要:

The generalized curves of closed loop peak magnitude, phase and frequency are derived here for a third-order control system. The regions in the parametric plane in which peak magnitudes exist and where the system is stable are also described

摘要:

The paper applies the theory of sensitivity analysis to a class of dynamical systems which possess hereditary influences. The analysis finds application in predicting or extrapolating the behaviour of a system subject to changes in its parameters about their nominal values. A sub-class of systems which lead to a mathematical formulation involving linear differential-difference equations is specifically considered. Computational schemes are given for the parametric and temporal influence functions.

摘要:

In this paper linear sampled data multi-variable synthesis is considered by the use of state difference equations. Murphy and Meksuwan's “1963” of approach is generalized for multi-variable systems. The non-interaction condition limits the achievement of dead-beat response depending on the nature of the input and the order of the individual transfer functions of the system. The method is general and can be applied to any polynominal input and also when non-linearities are present just after the compensator.
