There are four Control leverage in control Theory ：

*   Belief control system
    
*   Boundary control system
    
*   Interactive control system
    
*   Index control system
    

With the belief control system, the consciousness of boundary control can be generated, and interactive control will have clear logic, and the setting of the indicator will be more reasonable and easy to operate.
