介绍一种适用于非线性系统的反卷积算法.通过计算机仿真,一阶系统恢复信号相对平方误差在1%以内,相对阻尼系数为0.57~0.8的二阶系统恢复信号的相对平方误差在2%以内,可改善非线性系统的线性度和动态性能.通过振动测量实验验证,得到了较好的效果.该算法简单,在低频系统中可实时运行.
A deconvolution algorithm for nonlinear systems is introduced.Computer simulation shows that the relative square error of the first-order system recovery signal is within 1% and the relative square error of the second-order system recovery signal with relative damping coefficient is 0.57 ~ 0.8 is 2 %, The linearity and dynamic performance of the nonlinear system can be improved.The experimental results show that the proposed method is feasible and can be operated in real-time in low-frequency system.
