The governor is an automatic adjusting device that automatically increases or decreases the fuel supply of the fuel injection pump according to the change of the diesel engine load, so that the diesel engine can run at a stable speed. The governor has been widely used in industrial DC motor speed regulation, industrial conveyor speed …
Information is neither a substance nor an energy. It is a general term for exchanging content with the external environment when humans adapt to the external environment and when they are coping with the external environment. Therefore, it can be considered that information is a semaphore of an interactive communication between a person and the …
Definition The oscillator is simply a frequency source and is typically used in phase-locked loops. In detail, it is a device that can convert DC power into AC power without external signal excitation. Generally divided into positive feedback and negative resistance. The so-called “oscillation” implies the communication, and the oscillator contains a process and function …
Optimal control is the core of modern control theory. The main problem of its research is: Under the condition of satisfying certain constraints, the optimal control strategy is sought, so that the performance index takes the maximum value or the minimum value. Introduction The basic conditions and integrated methods for optimizing the performance indicators of …
Automatic control (principle) refers to the use of an additional device (called a control device or controller) to make a machine, device or a certain working state or the parameters (ie, the amount being controlled) of a production process (collectively referred to as the controlled object) automatically operate according to a predetermined rule. Related introduction …
Industrial automation is the various parameters in industrial production for control purposes, to achieve various process control. In the entire industrial production, the human operation is minimized, and the energy and various information other than animals can be fully utilized for production work, which is called industrial automation production. The process of enabling industrial automation …
