The intelligent controller is an indispensable "nerve center" in the intelligent control system, which mainly performs functions such as control information and feedback information. As a control unit in electronic equipment, devices, instruments and systems, the controller is at the core of the entire intelligent control system and plays a key role in the "nerve center".

      The intelligent controller is mainly composed of controllers, actuators, process objects, detectors and other parts. Among them, the detector is responsible for receiving and processing the output signal and converting it into a feedback signal, and the feedback signal and the input signal are input to the controller together; the controller processes the signal according to the pre-written intelligent control program to generate a control signal and transmits it to the actuator; finally The execution signal is output to the process object by the actuator.

      The current intelligent controller includes hardware and algorithms, and the core of the hardware is mainly MCU (microcontroller) chip/DSP (digital signal processing technology) chip. Specifically, the MCU chip appropriately reduces the frequency and specifications of the central processing unit, and integrates peripheral interfaces such as memory, counter, USB, A/D conversion, UART, PLC, and DMA on a single chip. Intelligent control algorithm to process the control system. MCU is not a chip that completes a single logic function, but integrates a computer system into a chip, which is equivalent to a microcomputer. DSP chip is a chip that can realize digital signal processing technology, with powerful data processing capability and high running speed. The interior of the DSP chip adopts the Harvard structure in which the program and data are separated, and has a special hardware multiplier, which can be used to quickly realize various digital signal processing algorithms. DSP is widely used in network equipment, power electronics, industrial control, smart home and other industries, and has become a basic device in communications, computers, consumer electronics and other fields.
