Time optimal control for a class of common random disturbances by
Rufus Oldenburger(
Book
)
2 editions published between 1969 and 1970 in English and held by 2 WorldCat member libraries worldwide
The paper concerns the time optimal control of a system variable where the controlling input is bounded, as is usually the case, and the system is subject to arbitrary disturbances. An arbitrary disturbance is made up of uncontrollable portions followed by controllable sections. In industrial practice controllers are sized, as for example as to power, to fit the system so that the disturbances encountered are primarily made up of uncontrollable sections followed by controllable portions of sufficient duration for the controller to bring the system equilibrium. The control designer wishes to have optimal control for any disturbance made up of such an uncontrollable portion followed by a sufficiently long controllable section. Here this problem is solved with the aid of the maximum principle for the class of second order systems which describe almost all governorengine applications to first approximation accuracy. Previous attempts to solve the problem involved assuming statistical properties of the disturbance thus severely restricting the class of applications. Here only those statistical properties required to implement optimal control are determined. A single control function is derived which suffices to yield optimal trajectories. (Author)

SELECTION OF A DELAY LINE MODEL(
Book
)
1 edition published in 1964 in English and held by 1 WorldCat member library worldwide
A mathematical model of a linear system can be derived using an approximation of the convolution integral. A model is selected such that responses to commonly occurring inputs are closest to corresponding responses of the system. The transfer function of the model is the product of the system transfer function by a linear combination of two delay terms divided by an infinite product. If the model delay time is small the infinite product may be replaced by 1, and thus may be dropped. The delay time and the number of delay elements are selected such that the responses of the simplified model are closest to corresponding responses of the system. The validity of the simplification is investigated for various inputs by comparing the responses of the simplified model with those of the exact model. It is found for several types of commonly occurring inputs that the number of delay elements should be chosen as large as physically possible. The results show that the value of the delay time should be selected as a function of the number of delay elements and of the system bandwidth. It is further shown that this function is the same for each of the inputs

Singular time optimal control by
Sadao Hayano(
Book
)
1 edition published in 1969 in English and held by 1 WorldCat member library worldwide
A slightly different definition of singular time optimal control from the usual sense is given here. A system is said to be singular if more than one optimal control exists for a given boundary condition. The characteristics of the newly defined singular control problem are studied where the system is assumed to be linear, time invariant and expressed by vector differential equations. The controls are Lebesgue measurable functions and belong to a compact convex set. It is demonstrated through example that Pontryagin's Minimum Principle is useful for the singular control problem. The minimum principle contains implicit information regarding the singular system. A standard procedure is shown to solve the singular problem. Methods of linear algebra are taken to analyze the system in this paper. (Author)

Identification of impulse response from normal operating data using the delay line synthesizer principle(
Book
)
1 edition published in 1969 in English and held by 1 WorldCat member library worldwide
A computational technique is presented for identifying the impulse response of a linear system from normal operating noisy data. No assumption, however, is made regarding the nature of the noise. The technique derives its idea from the Delay Line Synthesizer (DLS) though in this case the DLS coefficients which discretely represent the weighing function are computed automatically employing the steepest descent method. The method has been tried out on a first order as well as a second order system simulated on a digital computer and the estimated impulse response is found to be very close to the actual one.
