A closed loop path through which a working fluid is circulated includes a prime mover, such as a turbine (16), to which operating fluid in the vapor state is supplied from an evaporation chamber (10) which is partially filled with operating liquid. A condenser (14) is located adjacent the...
Closed-loop model checking, a formal verification technique for industrial automation systems, increases the richness of specifications to be checked and often helps to reduce size of the state space to be verified compared with the open-loop case. To be applied, it needs two components - the ...
In the application of the closed loop identification with the balanced truncation (BT) and the COIT methods; a numerical example and an inverted pendulum experimental system, the COIT method appropriately reduces the order of the estimated plant and controller models and is superior to the BT ...
Compared to previous research, this work (i) proposes a new modelling framework for identifying closed-loop systems, (ii) introduces a generic structure to represent the controller and (iii) explains how that the new framework gives rise to a simplified determination of the plant models. In ...
Particularly, the methodology is implemented in the N-Removal process of a Wastewater Treatment Plant (WWTP) and the results prove the efficiency of the method and that it can be used profitably in practical cases. 展开 关键词: WATER treatment plants CLOSED loop systems PREDICTIVE control systems...
In practice, many plants cannot be easily operated in open loop for carrying an experimentation protocol for identification (ex: integrator behaviour, drift, open loop unstable). In some situations,...Landau, I. D.GR-Automatique EnsiegLozano, R....
A closed loop extractor is a device for extracting a solvent from a solid matter. It is widely used in plant concentrates in industry. Throughout the process, several parts are used to extract the solvent. Solvents can be used and recycled in closed loop extractors, which is very ...
Without requiring an additional test, the primary controller is designed that accurately accounts for the inner loop dynamics. Two adjustable parameters in the proposed design can be used to deal with the trade-off between performance and robustness for inner and outer loops independently. The ...
This paper presents a closed-loop continuous-time subspace identification method using prior information. Based on a rational inner function, a generalized orthonormal basis can be constructed, and the transformed noises have ergodicity features. The continuous-time stochastic system is converted into a ...
