Control System Objectives

Pneumatic  actuators are not  as   messy  as hydraulic ones:-

Classification of  Robot  is  based on;-

At which  root  loci will end :-

Maximum  degree  of freedom  can be   six  in a  robot :-

Root  locus  is used to calculate :-

Controller   in a control system  amplify  the  signals going  to the  actuator:-

Primary purpose of  using  feedback  is  to reduce the sensitivity of the system  to parameter  variations:-

The  input   to  controller is  ;-

Open loop  transfer  function of  a  system  having  one  zero  with  a  positive  real value  is called :-

On which  factor  does  the  sensitivity  of  a closed  loop  system  to  gain  changes and  load  disturbances  depend:-

Which  principle does  the   linear system follow:-

The initial response when the output  is not  equal  to input is called :-

If the  impulse  response in absolutely  integrable  then the  system is  :-
