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

the pulse genrator is given for the refference and the block paramaters as amplitude 1 phase percentage is 50% and input is taken,here the the mass damper and spring equation is solved and it is taken into the account.the transfer function is taken and used for th simultion in the simulink and it is runned for 30sec.and the respected values and the graphs are shown below for better understanding.

the pid is implemented and the simultion is carried for the changes where we can observe the overshoot and the settling time the continous process etc
