MATLAB Dynamics & Control - Assignment ExampleFurthermore, both the date constant and dead time vary with the size of the step-change. The process gain is affected but it is affected only in half(a) of the cases (see Concentration A, see below). Select a set of dynamic process constants resulting from one of the step-changes that you have tested, and occasion these to calculate initial values for the constants in each of the three different interpretler equations (P, PI & PID). comparative control It is simple, provides rapid adjustment of the manipulated variable (MV). Does not provide zero smuggler, although the error is reduced (E0). It extend speeds in the dynamic response. It burn cause instability if improperly tuned.Integral control It is simple, achieves zero offset (E=0). It provides adjusts the manipulated variable (MV) in a slower manner than the proportional mode this can lead to ugly dynamic performance. It can cause instability if improperly tuned.Derivative con trol It is simple. It does not influence the last-place steady-state value of the error (E). It provides rapid correction based on the rate of change of the controlled variable (CV). It can cause undesirable high-frequency variation in the manipulated variable (MV). Once you have chosen your optimal control scheme, justify why you have selected it. You can use various methods of assessing controller performance in assure to reach your decision rise time, peak overshoot ratio, decay ratio, settling time, IAE, ISE, ITAE. You are not expect to use all of these, but at least two should be used and compared with each separate in relation to optimizing your controller constants. Test your control loop for its ability to cope with a disquiet (e.g. in the concentration of feed chemical, or the temperature of the cooling water), and also for its ability to move the process to a new operating region by making a step-change to the set-point (i.e.
