Question

Background: In this exercise, a feedback controlled system, utilizing a simplified model of a DC motor [with some mechanical load] is used to explore some of the characteristics of Simulink software DC Motor/Load Specifications: 0.01 0.1 0.1 10 0.5 Nm/rad/S, Motor and Load Inertia Nm/rad/S, Friction Motor constants (Kt-Ke-K) Ohms, Field resistance mH, Field inductance = Objective Given a simplified model of a DC motor [with some mechanical load] and input/output requirements 1. Simulate a feedback controlled system 2. Export results to Matlab 3. Write a single script to display results in several graphs Consider the following cases: 1) System without position and speed feedback (controller gain - 1) Input 0 to 10 volts (Step waveform) - Confirm your findings (slope vs speed and L/R). Show values as part of results 2) System with position feedback only (controller gain=0.1) Apply sufficient input such that motor will stop after 2.5 revolutions - Confirm your findings (stable response tracking input). Show values as part of results - Gradually increase controller gain and record your observations (change in time constant, rise time, overshoot, and oscillations) 3) System with speed feedback only (controller gain -1): -Input = 0 to 10 volts (Step waveform) - Confirm your findings (stable response). Show values as part of results - Gradually increase controller gain and record your observations (change in motor speed and time constant) 4) System with both position & speed feedback -Input = 0 to 10 volts (Step waveform) Adjust controller gain such that T

Explanation / Answer

#include<stdio.h>

int main()

{
  
   int i,MAX;
  
   int a[5];
  
  
  
   for(i=0;i<5;i++)
  
   {
      
       scanf("%d",a[i]);/* input 5 numbers */
  
   }  
  
   MAX=a[0];/*initialize the first number as maximum value*/
  
   for(i=0;i<5;i++)
  
   {
      
       if(a[i]>MAX)
      
       {
          
           MAX=a[i];
      
       }
  
   }
  
   printf("the maximum of 5 numbers is%d",MAX);

return 0;
