Abstract:
Based on the equivalent simplification of the closed cable loops (CCL), the principle of CCL synchronous deployment is analyzed and the mathematical model is established. The dynamic equation containing CCL is deduced in detail. Taking the synchronization analysis of a certain type of solar panels as an example, the dynamics of deployment and the cause of the large-scale non-synchronization are simulated and analyzed. The optimization model which is to minimize the asynchronous angle is set up and the parameters design of the driving torque is optimized by the sequential quadratic programming (SQP) algorithm. Compared with the traditional design method using the positive driving torque, the optimization results using the negative root driving torque parameters, reduce the loading of the linkage system effectively and improve the synchronous deployment of the solar panels.
