| 英文摘要 |
| For the output tracking control problem of discrete linear system with non-repetitive disturbance, a point to
point iterative learning control algorithm based on updating reference trajectory is proposed. Firstly, the iterative learning
controller is optimized by constructing performance index with norm function, and the corresponding convergence conditions
are given, then the system output can track with the desired points in updating reference trajectory. Furthermore,
when the system output is affected by non-repetitive disturbance in some trials, a new multi-objective performance index
function is constructed by Lagrange multiplier algorithm, and the robust iterative learning controller is optimized to improve
the convergence speed and tracking accuracy. Finally, the simulation results of the motor driven single mechanical
arm control system show the effectiveness and feasibility of the proposed algorithm. |
