Abstract

The invention discloses a digital servo control system which comprises a parameter monitoring unit, a servo execution unit, a display and IO equipment which are all connected with a servo data operation unit, wherein the parameter monitoring unit monitors parameters required by the servo control system and transmits data to the servo data operation unit; and through operation analysis of an internal specific control algorithm and a control strategy, a control signal is output to the servo execution unit, and the display and the IO equipment respectively display system data and an operating system instruction. Compared with the prior art, the digital servo control system and the control method have the advantages that accurate tracking can be realized, and the array can be subjected to state adjustment; and during tracking, cluster optimization control is performed on the whole array, so that the array can work in an optimal state.

Description

technical field [0001] The invention belongs to the technical field of servo control, in particular to a digital servo control system and a control method thereof. Background technique [0002] Solar energy is a kind of renewable energy. Human beings have a long history of using solar energy, and it has been widely used up to now. The most common one is the solar photovoltaic power generation system. The solar photovoltaic panel in the solar photovoltaic power generation system is a kind of The power generation device that will generate direct current is composed of solid photovoltaic cells almost entirely made of semiconductor materials (such as silicon), which can convert the sun's radiation into electrical energy. The main factors affecting solar energy collection are the intensity of sunlight, light Irradiation angle, light receiving area, etc., then the control system must consider these factors in order to better convert solar energy into electrical energy. Obviously, ...
