The servo control system is also known as the dynamic control system. The reference input is an arbitrary time function with unknown change rule. The task of the servo control system is to keep the controlled quantity in accordanc
Huaqing Vision LecturerWe know that embedded learning human eyes can see the visible light by wavelength from long to short arrangement, in turn, red, orange, yellow, green, green, blue, purple. The wavelength range of the red light is 0.62~0.76μm; The violet wavelength range is 0.38~0.46μm. The light that is shorter than the violet wavelength is called ultraviolet light, which is longer than the red wavelength is called infrared ray, see Figure 1. Infrared remote

In order to design the flight control system of unmanned rotor aircraft which can adapt to different flight tasks, the principle of model inverse controller is discussed. The Neural network compensation controller and its weight coefficient on-line algorithm are presented, and the stability of the integrated controller is analyzed. The inverse controller of rotational dynamics and the inversion dynamic inve
Key Points of user control design: System. Windows. Forms. UserControlKey Points of User Control Design A waterfall chart (color chart) function in a recent project is to present the point values in space and time in the form of graphs, such: X coordinates are space, and a pixel in the horizontal direction represents a space unit (for example, 50 meters) Y coord
PHP-based flow control system for RedisWe have a degree of micro-service transformation of the project module, before all modules are placed in a project (a large folder), the same as on-line deployment, such shortcomings are obvious. After we split into sub-modules according to the business function, and then the sub-modules through the RPC framework to access, each sub-module has its own separate online m

better understood, and those test-tested submissions would be selected for a more stable pipeline. You can maintain different levels of stability in this way. Some large projects also have a proposed (recommended) or pu:proposed updates (Recommended update) branch, which may not be able to enter the next or master branch because it contains some immature content. The goal is to have different levels of stability for your branches, and when they have some degree of stability, merge t
transmission rate. The maximum transmission rate in low-speed mode is 10.4 kbps. In medium-speed mode, the normal LIN transmission mode has a maximum transmission rate of 20 kbps. In high-speed mode, the maximum transmission rate is 40 kbps; the maximum transmission rate in Flash mode is 11 5 khps. to avoid interrupting the transmission process, the transmission rate cannot be changed in normal mode. The correct method is to disable the sending function first, then change the transmission rate,
