Abstract
The characteristics of bang-bang, proportional, integral, derivative, and PID controllers, and their applications to solar energy systems, are presented. Also included is a determination of the effects of temperature settings on cycling rates in systems using bang-bang controllers. A phase-plane representation is developed and an analytical representation for the number of cycles as a function of temperature settings, solar radiation, and physical parameters is presented.
Proportional and optimal control of mass flow rate in both low and high temperature applications is described. Examples are presented.
Finally, conventional, Proportional, and optimal controllers for off-peak storage systems are described. This analysis includes the electric utility in the system models.
Dr. Winn is a Professor of Mechanical Engineering and a member of the Solar Energy Applications Laboratory at Colorado State University. He has performed research and published articles in the areas of solar energy, orbital mechanics, satellite geodesy, remote sensing, hydrology and water resource systems, optimal control, and systems analysis. He has been actively involved in solar energy since 1973, served as General Chairman of the 1978 annual meeting of AS USES, has served on the Board of Directors of the Society and has chaired the Conference and Meetings Committee and the Nominations Committee. He is President of Solar Environmental Engineering Company of Fort Collins, Colorado, and has designed and installed a large number of solar systems and was the developer of the Solar Index.
Dr. Winn is also active in the American Society of Mechanical Engineering and serves as an Associate Editor of the ASME Journal of Solar Energy Engineering.
