Abstract In this assignment‚ lead compensator is implemented to reduce the percentage of peak overshot to less than 5% and the settling time to 2 second with 2% accuracy. First of all‚ to implement lead compensators into a circuit‚ a pole–zero pair is introduced into the open loop transfer function. Lead compensator is a component in a control system that improves an undesirable frequency response in a feedback and control system. Besides that‚ it also provides phase lead in its frequency response

Discussion and Conclusion: Preparation of 1-Bromobutane The purpose of this experiment was to demonstrate the conversion of a primary alcohol‚ 1-butanol‚ to a primary bromoalkane‚ 1-bromobutane‚ a SN2 reaction. The conversion of 1-butanol to 1-bromobutane relies on sulfuric acid which plays two important roles. First‚ it protonates the alcohol of 1-butanol to form an oxonium ion which is a good leaving group. Secondly‚ it produces the hydrobromic acid‚ the nucleophile‚ which attacks 1-butanol
