The mathematical model of electromechanical control system can take many forms, but usually the one that best describes the dynamic characteristics of the system is selected. In electromechanical control system, commonly used mathematical models include transfer function, state equation, frequency response and so on. These models can be used to describe the input-output relationship, dynamic characteristics and stability of the system.
For a specific electromechanical control system, the expression of its mathematical model depends on the complexity of the system and the selected modeling method. Simple control system can be described by transfer function, while complex control system may need to be modeled by state equation or frequency response.
In a word, the mathematical model of electromechanical control system does not have only one expression, but can choose different expressions to describe the dynamic characteristics of the system according to needs.
The mathematical model of electromechanical control system mainly includes time domain model, including differential equation and state space equation, which is used to describe the dynamic behavior of the system in time domain. Complex domain model: including transfer function and system block diagram, used to describe the frequency response and stability of the system; The frequency domain model includes a special mathematical model for dynamic control of electromechanical frequency transmission rate, which is used to describe the frequency response and stability of the system.
