This paper analyzes the performance of two parallel algorithms for solving the linear-quadratic optimal control problem arising in discrete-time periodic linear systems. The algorithms perform a sequence of orthogonal reordering transformations on formal matrix products associated with the periodic linear system, and then employs the so-called matrix disk function to solve the resulting discret...

Enhancement of the performance of a reverse osmosis (RO) unit through periodic control is studied. The periodic control manipulates the feed pressure and flow rate of the RO unit. To ensure the periodic behavior of the inputs, the manipulated variables (MV) are transformed into the form of sinusoidal functions. In this case, the amplitude and period of the sinusoidal functions become the surrog...

In this paper, the impulsive exploitation of single species modelled by periodic Logistic equation is considered. First, it is shown that the generally periodic Kolmogorov system with impulsive harvest has a unique positive solution which is globally asymptotically stable for the positive solution. Further, choosing the maximum annual biomass yield as the management objective, we investigate th...

used by TCP and other transport protocols — causes the transmission rate of a long-lived flow to oscillate. This paper is about the tendency of multiplexed flows on a bottleneck link to oscillate causing " aggregate periodic behavior ". As a consequence, bottleneck links can become underutilized, wasting capacity. One simple way to prevent this is to use larger buffers in the bottleneck router....

Modulated feedback control introduces periodicity. The global attracting property of the periodic points is established for a simple scalar discrete-time system under ∆-modulated feedback. Attracting regions of the periodic points are also characterized. When the discretization effects of the equivalent control based sliding mode control systems are studied, we show that the zero-order-hold dis...

Embedded systems are complicated, and a large number of these systems are widely used today. In embedded systems, the types of processings to be executed are limited, and many processes are executed periodically. In such systems, we need to reduce the overhead of periodic execution control and the dispersion of the processing time. ART-Linux has been proposed as a conventional real-time operati...

In this paper, an extremum-seeking controller is developed to steer a periodic system to orbits that maximize a functional of interest. The problem is posed as a real-time optimal trajectory generation problem in which the optimal orbit is computed using an extremum-seeking approach. The control algorithm provides tracking of the optimal orbit. A drug delivery system is considered to demonstrat...
