This paper presents an application of Dynamic Matrix Control (DMC) for controlling steam temperatures in a large-scale once-through boiler-turbine system. In order to control the steam temperatures, we choose a spray and a damper as two controllers. The step response model for the DMC is generated for the two major output variables, superheater and reheater temperatures, by performing step-input tests...
In the production of Hard Disk Drive (HDD), the pattern of HDD defect distribution gives the information about the defective component of HDD. This paper presents a pattern classification method for the HDD defect distribution. Five features of the pattern are developed and an Adaptive Neuro-Fuzzy Inference System (ANFIS) is applied to classify the input pattern. The ANFIS is trained with the sense...
This paper proposes an adaptive dynamic matrix control (DMC) using fuzzy inference and its application to boiler-turbine system. In a conventional DMC, object system is described as a step response model (SRM). However, a nonlinear system is not effectively described as a single SRM. In this paper, nine SRMs at various operating points are represented as fuzzy inference rules. On-line fuzzy inference...
This paper presents a technique that can obtain an optimal solution for the security-constrained economic dispatch (SCED) problems using the Interior Point Method (IPM) while taking into account of the power flow constraints. The SCED equations are formulated by using only the real power flow equations from the optimal power flow. Then an algorithm is presented that can linearize the SCED equations...
This paper presents a novel inference technique based on the semantic primitives for the development of intelligent load distribution systems. We use the term "load distribution system" in this paper to designate switchgears, feeders and loads for large buildings and apartment complexes after the MOF. With the rapid development of the techniques in the fields of communications and computers,...
