Depending on the values of \ud835\udc47 i and \ud835\udc47 d , the transfer function of the PID controller can have. real or complex valued zeros. Complex zeros might be useful for control of underdamped systems with complex poles. A PI controller is obtained from a PID controller by letting \ud835\udc47 d =0. Its transfer function is. \ud835\udc3a PI = \ud835\udc3e c 1+ 1 \ud835\udc47 i \ud835\udc60 = \ud835\udc3e c \ud835\udc47 i \ud835\udc60 1+ \ud835\udc47 i \ud835\udc60 (7.3) A PD controller is obtained from a PID controller by letting \ud835\udc47 i =\u221e. Its transfer function is. \ud835\udc3a PD = \ud835\udc3e c 1+ \ud835\udc47 d \ud835\udc60 (7.4) The ideal PID controller is sometimes referred to as. the parallel form of a PID controller. the (ISA) standard form.
