Answer: Comprehensive command level or system control level.
Answer analysis: In a hierarchical control system, different systems and applications may have different hierarchical divisions, but generally speaking, hierarchical control systems are organized from top to bottom and from abstract to concrete.
For the highest hierarchical control level, it can usually be called the comprehensive command level or the system control level, depending on the specific system type and application scenario.
Comprehensive command level/system control level
Function: This level is mainly responsible for overall decision-making and planning. It formulates global control strategies and task planning based on the overall goals and current status of the system. It is at the top of the hierarchical control system and has the highest decision-making power and control power.
Features:
+ High abstraction: The comprehensive command level mainly deals with the overall goals and strategies of the system, and does not involve specific execution details.
+ Strong decision-making: It needs to make global decisions and plans based on the overall needs of the system and environmental changes.
+ Great influence: The decisions and plans of the comprehensive command level will directly affect the operating status and performance of the entire system.
Other levels
In addition to the comprehensive command level/system control level, the hierarchical control system may also include other levels, such as the functional control level, execution level, etc. These levels play different roles in the system and work together to achieve the overall function of the system.
Functional control level: responsible for further refining the task plan formulated by the comprehensive command level into specific functional control instructions to guide the operation of the execution level.
Execution level: directly receives instructions from the functional control level and drives the system's actuators to complete specific operation tasks.
In summary, the highest hierarchical control level is usually the comprehensive command level or system control level, which is responsible for the overall decision-making and planning of the system and is the core of the hierarchical control system.
