| 摘 要： | 当采样周期 T→ 0时 ,Δ变换描述的离散模型收敛于连续系统。本文以汽车 AMT系统的离合器接合过程为控制对象 ,引入Δ变换离散描述 ,设计极点配置控制器 ,跟踪理想输出轴角速度。仿真结果表明 ,与 Z变换相比 ,在有限字长运算中 ,Δ变换受舍入截尾扰动的影响较小 ,但计算量稍有增大。

| Abstract: | A discrete model described by Δ transform converges to its continuous counterpart as sample time T→0. Δ transform was introduced into the clutch engaging process control in AMT of automobile. A pole placement controller to track the ideal angle velocity of output shaft. Compared with Z transform, Δ transform has better performance for round off noise caused by finite word length, but more calculations is needed. |
