Aservomechanism position control has the plant transfer function g(s) = 10 s(s + 1)(s + 10). you are to design a compensation transfer function d(s) in a unit feedback configuration to meet the following closed-loop specifications: • the response to a reference unit step input should have 16% overshoot (or less) and 0.4 sec rise time (or less). • the steady-state error to a reference unit ramp input must be less than 0.05. (a) design a lead compensator that will cause the system to meet the dynamic response specifications, ignoring the error requirement.

hello glad to meet you if you know the answer, what am i saying?

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
