Fast autotuning of process cascade controls
نویسنده
چکیده
A procedure is presented for the automatic tuning of cascade control systems. The main goal of the procedure is to achieve fast tuning, and moderate process upset. That goal is pursued by proper combination of an ad hoc relay-based identification procedure based on a single test, a specific controller structure, and a tuning rule based on a particular use of the IMC principle. Simulations are reported to illustrate the effectiveness of the proposal within its applicability limits, that are characterised as rigorously as possible (and may be widened by some of the envisaged extensions).

Autotuning of Parallel Cascade Control using Setpoint Relay
A new approach to tune the PI controller for parallel cascade control using setpoint relay autotuning method is proposed in this paper. The setpoint relay autotuning is found to be effective as that of the relay feedback method without switching off existing controller. The proposed method is found to be more advantageous for finding out ultimate gain and ultimate period and tested in computer ...
متن کاملTools for machine-learning-based empirical autotuning and specialization
The process of empirical autotuning results in the generation of many code variants which are tested, found to be suboptimal, and discarded. By retaining annotated performance profiles of each variant tested over the course of many autotuning runs of the same code across different hardware environments and different input datasets, we can apply machine learning algorithms to generate classifier...
متن کاملImproved relay auto tuning of P/PI controllers for unstable parallel cascade control systems
This paper focuses on simultaneous relay auto tuning of open loop unstable parallel cascade systems. For stable parallel cascade systems,Vivek and Chidambaram[1] had discussed effect of higher order harmonics of symmetrical relay output, which accounts for error in ultimate controller gain estimation. In the present work, this method is extended to parallel cascade controllers for open loop uns...
متن کاملPosition Control Improvement of Permanent Magnet Motor Using Model Predictive Control
Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...
متن کاملSingular Perturbation Theory in Output Feedback Control of Pure-Feedback Systems
This paper studies output feedback control of pure-feedback systems with immeasurable states and completely non-affine property. Since availability of all the states is usually impossible in the actual process, we assume that just the system output is measurable and the system states are not available. First, to estimate the immeasurable states a state observer is designed. Relatively fewer res...
