PDD205A1121 3BHEO25335R1121 Differs from the open loop control system

Compared with open-loop control system, closed-loop control has a series of advantages. In a feedback control system, no matter for what reason (external disturbance or internal change of the system), as long as the controlled quantity deviates from the specified value, the corresponding control effect will be generated to eliminate the deviation. Therefore, it has the ability to suppress the disturbance, is not sensitive to the change of component characteristics, and can improve the response characteristics of the system. However, the introduction of feedback loop increases the complexity of the system, and improper gain selection will cause instability of the system. In order to improve the control accuracy, when the disturbance variable can be measured, the composite control system is often used as a supplement to the feedback control.

PDD205A11213BHEO25335R1121 - generally speaking, the open loop control system structure is simple, the cost is low. The disadvantage of open-loop control system is that the control precision is not high, the ability to suppress interference is poor, and it is sensitive to the change of system parameters. It is generally used in situations where external influences or accuracy requirements are not considered, such as washing machines, stepper motor control devices and water level regulation systems.

PDD205A11213BHEO25335R1121 in closed loop control system, whether the change of the input signal, or the effects of interference, or within the system parameter change, as long as it is charged with quantity deviation from the specified value, produces the corresponding action to eliminate the deviation. Therefore, the closed-loop control has a strong ability to suppress the disturbance. Compared with open-loop control, the system is not sensitive to parameter changes, so less precise components can be used to form a more precise control system, and satisfactory dynamic characteristics and control accuracy can be obtained. However, the use of feedback device needs to add components, the cost is high, but also increases the complexity of the system, if the system's structural parameters are not appropriate, the control process may become poor, and even oscillation or divergence and other instability. Therefore, how to analyze the system, rationally choose the structure and parameters of the system, so as to obtain satisfactory system performance, is the problem that the automatic control theory must study and solve.
