Self-management and self-target process to achieve autonomous target of proactive self-adaptive behavior is an important research filed of artificial intelligence.In the paper,we propose a model of proactive self-adaptive behavior based on SOAR cognitive architecture.The problem process mechanism of SOAR cognitive architecture and learning mechanism are applied in this model. According to the task to design suitable operators in a particular problem space and use operators to achieve state transition,until the completion of the goal.The model is implemented in mobile robot’s behavior plan,application shows that robot can choice it’s behavior by itself to accomplish task.What’s more,we made a good simulation effect.
