摘要/描述

The electric thickness of the semi-finished radome may not meet the requirement for the electromagnetic performance because it varies with both the geometry thickness and the electric inductivity of the radome. One way to obtain the required value of the electric thickness is to compensate the electric thickness error by modifying the wall thickness of the radome. To this end, a grinding machine is developed and applied to precisely grind the inner surface of the radome. In order to ensure the grinding precision, it is important to keep the grinding machine under a stable, rapid and precise control. In this paper, a compound control strategy, which is a combination of the cascade control of 3-loop, the feedforward control and the PID algorithm, is proposed to realize a highly precise and reliable control over the grinding machine. Moreover, the architecture of the control system, the algorithm of the main controller based on DSP technology and the method of adjusting parameters are also introduced. It is shown that this compound control strategy has the advantages of high control accuracy and strong anti-jamming ability, being effective and applicable.
