When practicing the H-end (rhev-h) of the Red Hat Enterprise virtualization RHEV, it was found that it could only be installed on a physical machine and could not be installed in a virtual machine. After groping, by modifying some parameters, the RHEVH can be installed perfectly on the VMware workstation, so it is much easier to practice.The steps are as follows:650) this.width=650; "Src=" http://ugc.qpic.cn/adapt/0/de3d9619-d680-171d-84ba-aee7b76e2a1a/800?pt=0ek=1
In the previous article, the three constants in the PID algorithm play an approximate role in the PID algorithm, but in actual use, how to adjust the three PID control algorithms (or set them in more professional words. First, you can set all the three constants KP, KI, and KD to one and check whether the system's adjustment is too fast. Roughly determine the number of places that need to be shifted to the right of the output control result for the fi

The PID controller controls the crawling speed simply by increasing the speed, latency, and speed, reduce the delay time-have you seen the similarity between it and the fire condition described at the beginning of this article? Similar to the fire, I imagine the PID's solution for controlling crawler speed is:
1) initialization: Set the initial delay timeT0 and proportional coefficientKP (Classic-0.05)
2) target setting: Set

Given a positive integer p, any integer n must have an equation

Where K and R are integers and 0 ≤ r
For positive integers p and integers A and B, the following operations are defined:

Mod P addition :( a + B) mod P, the result is the remainder of A + B arithmetic and divided by P, that is, (a + B) = KP +
