摘要：
This paper describes the design of a sun tracker which uses two electro-optic sensors and a small, low-cost electronic control circuit. One sensor is a four-cell pyramid which is mounted on the tracker plane. The second sensor is a sunlight beam sensor which is fixed facing south. The control circuit tracking resolution is within 0.1 degrees. This system minimizes wandering on partially overcast days. It will never make multiple revolutions or face down towards the ground. Power MOSFETS (Metal Oxide Semiconductor Field Effect Transistors) are used to drive high-torque DC gearbox motors. © 1990.
