| 摘 要： | 为了从测量信号中恢复出原始的物理信息 ,需要设计动态测量系统的逆系统 ,以使整个系统的传递函数为 1。但对于非最小相位测量系统 ,简单的逆变换会引起系统不稳定 ,零相位误差算法的引入有效地解决了这个问题。文中以温度测量为例 ,对其进行反演 ,仿真表明结果真实可靠 ,方法具有一定的实用价值

| Abstract: | In order to rebuild the original physical information from the measurement signal,the inverse system of dynamic measurement system should be designed.The general transfer function of the whole system is then to 1.However,for nonminimum phase system,the straight inverse transformatiom will cause the system unstable.Zero phase error algorithm is then introduced to solve this problem.Temperature measurement is taken as examples to be rebuilt.Simulation shows the results are credible and the method has practical values. |
