Project - Speed Control of a Direct Current (DC) motor

here we done an project on the4 speed control of the dc motor by using the PID contoller

first we designed the dc motor modal design by using the simulink modal where we have use these blocks

BLOCKS USED

CLOCK - used to give clock pulse input to the timespace block

TIMESPACE- which is used to take and give the values from the workspace

SUMMATION-it is uded to summ the two blocks

GAIN BLOCK-used for the feedback system here to give back emf

STEPINPUT-input ranges from 0 to 230 is given through this block

SCOPE-used to see trhe output of the modal

TRANSFER FUNCTION=which is used to take the numerator value as 1 and denominator values

CONNECTION.

the input as 230 voltage is given through the step input block and is given to the summation block where it has two inputs another is get from the feedback block and the output of the sumation block is given to the transfer function block wherethe output is taken as the armatrure current and this output is given to thetorque constant gain block where the output is taken asthe torque value and again it isgiven to the another transfer function block where it is taken as the output speed

finally .m file scvreenshot has been placed and .slx file is attached below outputs are also shown..
