1, PID is a closed loop control algorithm. Therefore, to achieve the PID algorithm, you must have the hardware loop control, that is, must have feedback. Such as controlling a motor speed, you have to have a measurement of speed sensor, and the results fed back to the control line, ...
When you change the design focus, the algorithm attempts to adjust the gains to favor either reference tracking or disturbance rejection, while achieving the same minimum phase margin. The more tunable parameters there are in the system, the more likely it is that the PID algorithm can achieve ...
the tuning algorithm chooses a controller design that balances the two measures of performance, reference tracking and disturbance rejection. You can change the design focus to favor one of these performance measures. To do so, usetheDesignFocusoption ofpidtuneat the command line ortheOptionsdialog...
adding water to the water tank with a bucket to control the height of the water level. If you simply use the proportional control algorithm, assuming比例P系数is 0.5 (equivalent to两桶水的容量equal to一缸水的容量), we start to simulate the water addition experiment: ...
I’ll then improve it step-by-step until we’re left with an efficient, robust pid algorithm. The Beginner’s PID Here’s the PID equation as everyone first learns it: This leads pretty much everyone to write the following PID controller: ...

Eq. (1) shows that the algorithm based on the equally spaced forward-difference Newton’s interpolation polynomials only utilizes the previous sampling points. Therefore, the “on-line” control can be achieved. Namely, the differential of the point y0y0 is estimated from the target-function’s...
