Detecting Process V Ariations in Low-end Pid Autotuners
نویسندگان
چکیده
This paper presents a tec hnique for detecting process dynamics variations with barely essen tial computational resources, thus applicable in very low-end autotuning regulators. The method is based on the online computation of convenient indexes, compared to nominal values obtained in the tuning phase. After describing the procedure, the results of its validation on a linear test batch, a test in a nonlinear case and some experimental results are brie y reported.

The paper presents theoretical insights which might lead to further development of improved relay-based PID autotuners. The analysis is based on the first generation of autotuners, namely the widely used Åström-Hägglund relay-feedback tuner. The analysis is accompanied by illustrative examples. The performance of the autotuners is evaluated against a reference PID controller which is designed u...
متن کاملSimple Model-based Pid Autotuners with Rapid Relay Identification
Based on some relationships between modeland relay-based PI/PID tuning, some very simple synthesis procedures are proposed that couple the advantages of model-based methods to the simplicity and clarity of relay experiments. These procedures are fast, as they employ a single relay test, and do not introduce large process upsets. They are also very light from the computational standpoint, thus w...
متن کاملSmith Predictor Based Autotuners for Time-delay Systems
This paper presents a set of autotuners for single input-output systems with time delay. Autotuners represent a combination of relay feedback identification and some control design method. In this contribution, models with up to three parameters are estimated by means of a single asymmetrical relay experiment. Then a stable low order transfer function with a time delay term is identified. Contr...
متن کاملThe Next Generation of Relay-Based PID Autotuners (PART 2): A Simple Relay-Based PID Autotuner with Specified Modulus Margin
The purpose of this paper is to present the development and evaluation of a novel PID autotuner. Based on prior art results, the algorithm uses the location of the critical point and the value of the critical frequency of the process to impose a user specified robustness on the closed loop. It is shown that the method is easy to apply with few choices left for the user. Nevertheless it is quite...
متن کاملAutotuning Principles for Time-delay Systems
This paper presents a set of single input – output (SISO) principles for tuning of continuous-time controllers used in autotuning schemes. The emphasis of designed autotuners is laid to SISO systems with time delay. Autotuners represent a combination of relay feedback identification and some control design method. In this contribution, models with up to three parameters are estimated by means o...
