. 3. For the heatexchanger system in CStation (Assignment 3, Exercise 5), we would like to implement a feedback control system using a PID controller by controlling the temperature with the cooling water as the manipulated variable. 1. 2. 3. 4. Find the characterist ic equat ion Find the ultimate controller gain ( k cu ) Design a PID controller using the Cohen and Coon and ZN tuning methods Analyze the closedloop response against setpoint and disturbances changes Solution...
