(a) For the case of the digital velocity P and PD algorithms, show how the set point enters into calculation of ∆pk on the assumption that it is not changing, that is, is a constant
(b) What do the results indicate about use of the velocity bun of P and PD digital control algorithms?
(c) Are similar problems encountered if the integral mode is present, that is, with P1 and PID forms of the velocity algorithm? Explain.
