摘要
对于伺服系统,转动惯量辨识在整定调节器参数和调节系统性能上有重要意义。针对一种小惯量系统的情况,考虑实现的难度,常用的辨识方法精度不够高。采用了一种高精度的朗道离散时间递推算法来实现惯量辨识,充分提高了辨识精度。虽然增加了计算的复杂性,但是依赖DSP的强大运算能力还是可以轻松实现。仿真和实验验证都取得了良好的效果。
Inertia identification of servo system has important significance in tuning control parameter and regulating system performance. For a small-inertia system, if we take the difficulty to realize into consideration, the commonly used identification algorithm is not precise enough. A high-precision Landau discrete- time recursive algorithm was applied to realize inertia identification with a high precision. Although the algorithm make calculation complex, with the power operation ability of DSP, it is nevertheless easy to realize. The simulation and experiments show that the result is satisfactory.
