A negative unity feedback loop with input R(s), output Y(s) and error E(s) is placed around the system \(H(s)=1/((s+p_{1})(s+p_{2})...(s+p_{q}))\)
(a) Find the transfer function E(s)/R(s).
(b) For this system to respond to inputs of the form r(t)=t^n (t=>0 and n<q) with zero steady-state error, what constraints are placed on the open-loop poles p.1 .... p.q?
A 1.8-kW electric heater takes 15 min to boil a quantity of water. If this is done once a day and power costs 10 cents/kWh, what is the cost of its operation for 30 days
Two balanced Y-connected loads in parallel, one drawing 15 kW at 0.6 power factor lagging and the other drawing 10 kVA at 0.8 power factor leading, are supplied by a balanced, three-phase, 480-volt source.
