低成本小型化冲击检测系统的模糊补偿算法
A fuzzy compensation algorithm for low-cost miniaturization shock test system
摘要
Abstract
In the field of vibration and shock signal testing,piezoelectric sensors tends to match with ICA104 charge amplifier to form a low?cost miniaturization detection system. The low?cost miniaturization shock test system has the defects of delayed re?sponse,response amplitude attenuation and other disturbances,whose dynamic characteristics are difficult to meet the require?ment of real?time detection. Therefore,a fuzzy adaptive PID compensation algorithm based on fuzzy control theory is proposed. The fuzzy rules of improving the membership function distribution is used in the algorithm to calculate the constantly?changing deviation and its change rate of the system to realize the online self?modification of three parameters for PID,so as to ensure that the algorithm can adapt to the change of the system itself or the outside and compensates the system in an optimal state all the time. The results of simulation and experiments illustrate that the algorithm can track the calibration signal well,the ampli?tude response of the system after compensation is increased by 14.7%,the response starting time is advanced by 0.4 ms,the peaking time is decreased by 0.21 ms and the regulation time is shortened by 3.8 ms,so as to achieve the purpose of compensat?ing the system and optimize the real?time performance,tracking accuracy and other dynamic characteristics of the detection sys?tem.关键词
