China's industrial automation market players by the major integrators, software and hardware manufacturers, system, product distributors, and other components. Hardware and software products in the field of industrial product sales of the manufacturers, almost all of the high-end market dominated by well-known foreign brand products, Wing City industrial products, and still maintain such a situation; in systems integration, multinational companies occupy the high-end manufacturing, has The company occupies a strong industry background in related industries systems integration business initiative, system integration company has extensive experience in application of full competitiveness. In the industrial automation market, there is a misalignment between supply and demand. Customers need to meet their own complete manufacturing process of electrical control system, the price of industrial products, and suppliers of a variety of standardized device products. Different industries, differences in electrical control is very large, even in the same industry because of their different customer demand due process are quite different. This contradiction between supply and demand for the industrial automation industry has created space for development. Open-loop control system in the open-loop control system, the system output by only control input, industrial product sales prices, control accuracy and interference suppression characteristics than the poor. Open-loop control system, based on the chronological logic control is called the sequential control system; the sequence control means, detection elements, actuators and controlled industrial objects formed. Mainly used to control and robotic and automatic production line machinery, chemicals, material handling and transportation process. Closed-loop control system closed loop control system is built on the basis of the principle of feedback, use the same amount of deviation of the output expected value to control the system, get better control performance. Closed loop control system, also known as a feedback control system. A given signal classification, automatic control system can be divided into constant control system, servo control systems and process control systems. Constant setpoint change control system requires a certain amount of system output accuracy close to the system given desired value. As the production process of temperature, pressure, flow, liquid level, motor speed and other automatic control system belongs to the permanent value of the system. Servo control system setpoint by an unknown function of time is required to follow the change in the output setpoint. If with satellite radar antenna system. Process control system for a given value by a certain function of time. Such as program-controlled machine tools.
