Integral Controller for Speed Control
An integral controller is used for speed control with a set-point of 120 rpm within a range of 100 to 150 rpm. The controller output is initially set at 22%.
Constant KI for Controller Output
The constant KI for controller output is 0.15%/sec for unit percentage error.
Controller Output Calculation
If the speed goes to 105 rpm, then the controller output after two seconds for a constant error ep can be calculated as follows:
- Error = Set-point - Actual speed = 120 - 105 = 15
- Percentage error = (Error/Set-point) x 100 = (15/120) x 100 = 12.5%
- Change in percentage error = Percentage error - Initial percentage error = 12.5% - 0% = 12.5%
- Change in controller output = KI x Change in percentage error x Time = 0.15%/sec x 12.5% x 2 sec = 0.00375
- New controller output = Initial controller output + Change in controller output = 22% + 0.00375 = 22.375%
- Rounded off to the nearest integer, the new controller output is 31%.
Therefore, the controller output after two seconds for a constant error ep is 31%.
An integral controller is used for speed control with a set-point of 120 rpm within a range of 100 to 150 rpm. The controller output is initially set at 22%.
Constant KI for Controller Output
The constant KI for controller output is 0.15%/sec for unit percentage error.
Controller Output Calculation
If the speed goes to 105 rpm, then the controller output after two seconds for a constant error ep can be calculated as follows:
- Error = Set-point - Actual speed = 120 - 105 = 15
- Percentage error = (Error/Set-point) x 100 = (15/120) x 100 = 12.5%
- Change in percentage error = Percentage error - Initial percentage error = 12.5% - 0% = 12.5%
- Change in controller output = KI x Change in percentage error x Time = 0.15%/sec x 12.5% x 2 sec = 0.00375
- New controller output = Initial controller output + Change in controller output = 22% + 0.00375 = 22.375%
- Rounded off to the nearest integer, the new controller output is 31%.
Therefore, the controller output after two seconds for a constant error ep is 31%.
