The Simulation Analysis on Closed-Loop PID-Type Iterative Learning Algorithm of Linear Time-Varying System

对闭环PID型迭代学习算法进行了收敛分析,并针对一类线性时变系统,分别运用开环和闭环PID型迭代学习算法进行了仿真研究。仿真结果表明,闭环比开环PID型迭代学习算法更能较快地跟踪期望轨迹,而且很少出现不稳定的现象,在收敛速度方面显示了该算法的优越性。

In this paper,a closed-loop PID-type iterative learning scheme for a class of linear time-varying system is analyzed.Then,a concrete mode is simulated by this scheme and open-loop PID-type iterative learning scheme respectively.The simulation results indicate that the closed-loop scheme can trace desired locus more quickly and improve stability of the system more effectively.The scheme is better than the open-loop scheme in terms of convergent speed.
