Automatic control program creation using concurrent Evolutionary Computing
… relatively simple, non safety -critical embedded control applications, GP can be used as a practical alternative to software developed by humans. Embedded control software has become a branch of software engineering with distinct temporal, interface and resource constraints and requirements. This …

Synchronization via correlated noise and automatic control in ecological systems
… nonlinear systems via correlated noise and automatic control. The thesis is divided into two parts. The first part is motivated by field studies on feral sheep populations on two islands of the St. Kilda archipelago, which revealed strong correlations due to environmental noise. For a linear …

Human and automatic control interaction with a remotely piloted vehicle
… from a study on the performance of humans and automatic controllers in a general remote navigation task. The remote navigation task is defined as driving a vehicle with nonholonomic kinematic constraints around obstacles toward a goal. We conducted experiments with humans and automatic …

Automatic Control of Chemical Application Rate With Soil Organic Matter and Travel Speed as Inputs (Microprocessor, Digital Control)
Effective and efficient control of agricultural chemical application rate will allow a reduction in the use of pesticides for proper pest control with less environmental contamination. A microprocessor based sprayer control system was developed to regulate chemical application rate according to the …

Analog computer simulation of sampled-data systems
… is widely used to simulate most types of automatic control systems, Only a limited amount of work has been reported, however, involving analog computer simulation of sampled-data systems, This is to be expected since such systems are essentially digital in nature. The purpose of the work …

Experimental evaluation of some feedforward control models for binary distillation
In this study four different feedforward control models were derived in order to hold overhead composition fixed. This task was performed by literature review on distillation dynamics and simulation, and automatic control system applications. A theoretical analysis of feedback control compared to …

Application of Dirichlet Distribution for Polytopic Model Estimation
… (PM) structure is often used in the areas of automatic control and fault detection and isolation (FDI). It is an alternative to the multiple model approach which explicitly allows for interpolation among local models. This thesis proposes a novel approach to PM estimation by modeling the set …
