Description: In this paper, in control theory, sliding mode control, or SMC, is a form of variable structure control (VSC). It is a nonlinear control method that alters the dynamics of a nonlinear system by application of a high-frequency switching control. The state-feedback control law is not a continuous function of time. Instead, it switches from one continuous structure to another based on the current position in the state space. Hence, sliding mode control is a variable structure control method. The multiple control structures are designed so that trajectories always move toward a switching condition, and so the ultimate trajectory will not exist entirely within one control structure. Instead, the ultimate trajectory will slide along the boundaries of the control structures. The motion of the system as it slides along these boundaries is called a sliding mode and the geometrical locus consisting of the boundaries is called the sliding (hyper) surface Platform: |

Description: 演变过程
自抗扰控制器自PID控制器演变过来，采取了PID误差反馈控制的核心理念。传统PID控制直接引取输出于参考输入做差作为控制信号，导致出现响应快速性与超调性的矛盾出现。
折叠编辑本段组成部分
自抗扰控制器主要由三部分组成:跟踪微分器(tracking differentiator)，扩展状态观测器 (extended state observer) 和非线性状态误差反馈控制律(nonlinear state error feedback law)。(The evolution process
The PID controller (adrc) evolution, took the core idea of PID error feedback control.Traditional PID control direct speech output to the reference input do bad as control signal, resulting in response to the contradiction between quickness and super tonality.
Folding editing this section component
(adrc) is mainly composed of three parts: the tracking differentiator (tracking differentiator), extended state observer (extended state observer) and nonlinear state error feedback control law (nonlinear state error feedback law).) Platform: |
