什么是『自适应控制』?
What is 'adaptive control'?
自适应控制在运行中在线估计系统参数并自动调整控制器,使对象特性随时间或工况变化时仍保持良好表现,常用于飞行器、机器人和工况多变的工业过程。
Adaptive control estimates parameters online and retunes itself during operation, keeping performance as the plant changes over time or conditions—used in flight, robotics, and varying industrial processes.

PID控制器中的比例、积分、微分各解决什么问题?
What do the proportional, integral, and derivative terms in a PID controller each address?
比例项按当前误差大小给出纠正力度;积分项累计历史误差以消除稳态余差;微分项依据误差变化率提前抑制超调。三者配合可在多数过程控制中取得平稳响应。
The proportional term reacts to current error; the integral accumulates past error to wipe steady-state offset; the derivative anticipates via error rate to curb overshoot. Together they give smooth control in many processes.

控制中的『鲁棒性』是什么?
What is 'robustness' in control?
鲁棒性指控制器在模型不准、参数漂移或存在外界扰动时仍能保持良好性能的能力。设计鲁棒控制器就是要让系统在不确定性下也不易失稳或失效。
Robustness is a controller's ability to keep performing well despite model error, parameter drift, or disturbances. Robust design keeps the system stable and effective under uncertainty.

奈奎斯特稳定判据是怎样只用开环数据判断闭环稳定性的?
How does the Nyquist stability criterion judge closed-loop stability from open-loop data alone?
奈奎斯特判据看开环频率响应的复平面轨迹如何绕过点 (-1,0),结合右半平面开环极点数判断闭环是否稳定,无需先求出闭环特征方程。它在存在时延和不确定时尤其有用。Nyquist 在 1932 年提出这一思想。
The Nyquist criterion looks at how the open-loop frequency-response locus encircles the point (-1,0) and, with the count of right-half-plane open-loop poles, decides closed-loop stability without solving the characteristic equation. It is valuable when delays and uncertainty are present. Nyquist proposed it in 1932.

什么是“负反馈”?它为何能提升系统的稳定性与精度?
What is negative feedback, and why does it improve a system's stability and accuracy?
负反馈把输出的一部分减去后送回输入端,从而减小对参数变化的敏感度、拓宽带宽并降低失真。但若相位滞后过大则可能引发振荡,需用奈奎斯特/伯德判据分析稳定性。
Negative feedback subtracts a portion of the output from the input, reducing sensitivity to parameter variations, widening bandwidth, and lowering distortion. But excessive phase lag can cause oscillation, so stability is analyzed with Nyquist or Bode criteria.

How does the Kalman filter estimate states that cannot be measured directly?

What is feedback and why does it stabilize a system?
反馈是把系统输出的一部分送回输入端,与设定目标比较产生纠正动作。负反馈能抵消偏离,使温度、速度等保持在目标附近,是大多数稳定控制的基础。
Feedback sends part of a system's output back to its input to compare with the target and produce correction. Negative feedback counteracts deviation, holding temperature, speed, and the like near the goal, the basis of most stable control.

控制里说的系统『稳定』是什么意思?
What does 'stability' of a system mean in control?
稳定指系统受扰动偏离平衡后,能在有限时间内回到或接近原状态;不稳定则会持续发散或振荡。稳定性是控制器设计首先要保证的性质。
Stability means a system perturbed from equilibrium returns or stays near it in finite time; instability means it diverges or oscillates without bound. It is the first property a controller must guarantee.

开环控制按预定指令执行、不测输出,简单但不抗干扰;闭环控制测输出并反馈比较,能自动纠偏,所以多数精密系统用闭环。
Open-loop acts on preset commands without measuring output—simple but disturbance-prone. Closed-loop measures output and feeds it back to correct, so precision systems use it.
