PID controller design

A recent addition to the model-based tuning correlations is Internal Model Control (Rivera, Morari, and Skogestad, Internal Model Control 4 PID Controller Design, lEC Proc. Des. Dev., 25, 252, 1986), which offers some advantages over the other methods described here. However, the correlations are similar to the ones discussed above. Other plant testing and controller design approaches such as frequency response can be used for more complicated models. 

The proposed formulation addresses the problem of PID controller design solely in the time domain. It is important to...

This chapter presents a new PID controller design method based on process frequency response information. The novel ideas lie in the way that the closed-loop performance is specified via the desired response of the control signal and in the use of only two process frequency response points in the design. The relationship between the process frequency response and its step response, developed in Chapter 5, is exploited here to determine the frequency information to be used for controller design. 

One of the most common features of many PID controller designs is that performance is specified in terms of the trajectory of the desired closed-loop process output response to a setpoint change. Here, we propose to specify the closed-loop performance in terms of the desired behaviour of the controller output or control signal in response to a setpoint change. 

We now present our PID controller design specifications for two types of processes frequently encountered in the process industries. 

Our goal for PID controller design is to achieve the desired closed-loop, time domain performance with respect to both the process output variable and the control signal responses. The key is to be able to link the frequency domain controller design with the time domain performance specification. To make this link, we examine the relationship between the desired...
