| 英文摘要 |
| The design of variable structure control using the reaching law approach for uncertain discrete time systems was discussed. The reason for system chattering of conventional reaching law was studied and a new control strategy with perfect performance was proposed. The new method was applied to a position servo system. Theoretical analysis and simulation results showed that the controller designed can weaken the chattering effectively and provide the servo system with perfect tracking ability and strong robustness. |
