摘要
带宽是伺服系统的一项重要指标。为了确定系统是否满足要求,需要定期对包括系统带宽在内的指标进行测试。一般首先测试系统的频率特性,再根据频率特性得到系统带宽。采用一种单位脉冲响应的方法,实现对伺服系统带宽的测试。仿真结果表明,采用单位脉冲响应的方法能减少实验次数,同时得到的系统带宽与理论带宽之间的误差较小。
The bandwidth is an important performance requirement for the servo system. In order to determine whether bandwidth need to its performance is acceptable for required properties, the test of indicators including be tested. Generally, test the system frequency characteristic first; finally the bandwidth is got according to frequency characteristic. A method izes the test of bandwidth for servo adopting this method. At the same system. The results show time, the errors between impulse response is used, that the number the bandwidth of experiments is of simulation and which real- reduced by theoretical bandwidth are very small.
