microprocessor speed controller.

Available input is (24v dc)

i want the variable transformer out put ranging ( 4v(min) to [url removed, login to view](max) ) 3 Amp

1st selection ( 5.5 v ) which is in actual getting ( [url removed, login to view])

starting from [url removed, login to view] , it must gradually increase and have a time delay of 120 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach [url removed, login to view] .

2nd selection ( 6v )which is in actual getting ( [url removed, login to view])

starting from [url removed, login to view] , it must gradually increase and have a time delay of 120 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach 6v

3rd selection ( [url removed, login to view] )which is in actual getting ( [url removed, login to view])

starting from [url removed, login to view] , it must gradually increase and have a time delay of 120 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach [url removed, login to view]

4th selection ([url removed, login to view])

starting from [url removed, login to view] , it must gradually increase and have a time delay of 120 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach [url removed, login to view] .

5th selection (7v)

starting from [url removed, login to view] , it must gradually increase and have a time delay of 120 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach 7v .

6th selection (7.5)

starting from [url removed, login to view] , it must gradually increase and have a time delay of 110 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach 7v .

7th selection (7.8)

starting from [url removed, login to view] , it must gradually increase and have a time delay of 110 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach [url removed, login to view] .

8th selection (8v)

starting from [url removed, login to view] , it must gradually increase and have a time delay of 110 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach 8v .

9th selection (8.5)

starting from [url removed, login to view] , it must gradually increase and have a time delay of 110 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach [url removed, login to view] .

10th selection (8.8)

starting from [url removed, login to view] , it must gradually increase and have a time delay of 110 seconds to reach [url removed, login to view] , once it reaches the value then it must go in normal speed to reach [url removed, login to view]

Note :

This is actually to control a servo valve for the flow of oil .

so on each selection , it would be recommendable to have that speed adjustment in analog type . if you would ask for an approx range ( 50 to 200 ) . as for each selection/model the speed might differ .
