Hello, im never one to ask for help but i have been unable to attend lectures on this subject, i have very little time to complete this(tomorrow). im not looking for someone to answer it for me more guidance on how i go about completing this, many thanks
hello, ive missed this semester due to not being able to attend, i've still been doing my own learning but have yet to even begin on this topic, ive searched online and read books but i dont even know where to begin, any help or a starting point would be much appreciated.
A concentration control loop in an industrial chemical process can be represented by a second order dynamics with a long transmission delay. The two time constants of the second order dynamics are T1 = 4 min and T2 = 6 min respectively. The steady state gain is 5 and the dead time is 12 min. The loop is to be controlled to achieve a desired dynamics of first order with time constant Td = 2 min and zero steady-state offset for a step reference. Produce solutions to the following questions.
Identify the plant transfer function and the desired closed-loop system transfer function. Then, design a feedback control system with the controller designed using Direct Synthesis method, where the time-delay is approximated using the first-order Taylor expansion. Implement the controller with a standard industrial PID controller.
