Abstract

The invention discloses a space solar power station sun tracking model movement control system comprising a flexible cable supporting system which enables a sun tracking / light concentrating mechanism to move to the target position and attitude by using a six-cable parallel mechanism and performs sun tracking movement; the sun tracking / light concentrating mechanism which performs sun tracking movement under driving of flexible cables for collecting sunlight; a control system which is used for realizing accurate positioning of the sun tracking / light concentrating mechanism and using an improved interpolation fuzzy control algorithm based on a nonlinear tracking differentiator; and a measurement system which realizes tracking measurement of the sun tracking / light concentrating mechanism by using a Leica measuring instrument and a 360-degree prism and outputs the actually measured data to a dedicated movement control card in real time. The space solar power station sun tracking model movement control system is high in reliability, great in stability, low in cost, flexible in control mode, extensible and great in control effect and can simulate operation of the real system in the space so as to collect sunlight at the maximum efficiency.

Description

technical field [0001] The invention belongs to the technical field of electromechanical-optical integration design, and in particular relates to a space solar power station and solar model motion control system. Background technique [0002] The space solar power station (SSPS) is developed based on the space solar power technology. The most primitive prototype is the solar power satellite (SPS) concept in Peter Glaser's doctoral dissertation in 1968. It is planned to build a space at an altitude of about 36,000 kilometers from the ground. Solar power plants use satellites to gather solar energy in space, and then transport the concentrated energy to the ground continuously, and then convert it into electrical energy for human use. The intensity of sunlight in space is 5-10 times greater than that on the ground. Space solar power generation technology can provide constant energy, which is different from the intermittent use of solar energy on the ground, which is greatly af...
