Type 0, Type 1, Type 2 and Type 3 System's Polar Plot With Examples
Drawing Polar Plot Directly from Type and Order of System
Effect of Adding pole at origin and simple pole to O.L.T.F. of System
Pole at origin shifts starting point 900 Clock wise direction.
Simple pole adds a 900 Clock wise rotation to End point.
Starting Point of Polar Plot depends on Type of System.
Terminating Point of Polar Plot depends on Order of System.
This method is only applicable if only poles are present in open loop transfer function G(s)H(s) of system.
