Optimization of Control Parameters Using Improved Relay ...

For improved relay tuning, two parameters i.e. relay height (h) as 0.2 and number of harmonics (N) as 5 was considered for experimentation. The experiments were conducted and the corrected ultimate gain (Ku) was calculated. The actual value of Ku by amplitude criteria is 7.22. And the calculated Ku by conventional and improved relay
