Abstract—The proportional integral derivative (PID) controller

is the most widely used control strategy in industry. The

popularity of PID controllers can be attributed partly to their

robust performance in a wide range of operating conditions and

partly to their functional simplicity. This paper presents design of

PID controller using Ziegler-Nichols (ZN) technique for higher

order system. A Fuzzy logic controller using simple approach &

smaller rule set is proposed. Simulation results are demonstrated.

Performance analysis shows the effectiveness of the proposed

Fuzzy logic controller as compared to the ZN tuned PID controller

& fine tuned PID controller.
