Robust Control of Heat Exchangers

Chemical Engineering Transactions, 2012
This work deals with the design and application of a neuro-fuzzy controller to a heat exchanger and with possibilities to use the coefficient diagram method for heat exchanger control. The heat exchanger is a tubular one and it is used for pre-heating of

Motor speed control system design considering a trade-off between response speed and noise reduction

Nihon Kikai Gakkai ronbunshu, 2016
This paper proposes an automatic tuning method for a motor speed control system. Parameters of a PI controller and a low-pass filter (LPF) for motor speed signal are automatically derived satisfying required specifications of a time constant of step ...

DESIGN OF CDM-BASED CONTROLLER FOR INTEGRATING PUMPED TANK PROCESS, ITS COMPARATIVE SETPOINT TRACKING PERFORMANCE, AND DISTURBANCE REJECTION CAPABILITY

Electrica, 2009
Integrating processes are non-self regulating and very difficult to control. The pumped tank process is an example of such processes. In this paper, first of all, first order plus dead time (FOPDT) integrating model of the pumped tank process is obtained

Improved Detection of Myositis‐Specific Autoantibodies Using Luciferase Immunoprecipitation Systems Assay: Comparison With Line Blot and Conventional Immunoprecipitation

Arthritis &Rheumatology, EarlyView.
Objective Myositis‐specific autoantibodies guide the diagnosis and classification of idiopathic inflammatory myopathies, but current immunoassays vary in accuracy, particularly for autoantibodies associated with interstitial lung disease. To compare the performance of the luciferase immunoprecipitation systems (LIPS) assay with line blot and ...

Early and High‐Dose Glucocorticoid Use and Survival in Advanced NSCLC Receiving Immune Checkpoint Inhibitors: A Multicenter Target Trial Emulation

Clinical Pharmacology &Therapeutics, EarlyView.
Despite the immunomodulatory mechanism of immune checkpoint inhibitors (ICIs), systemic glucocorticoids are commonly used in advanced non–small cell lung cancer (NSCLC). Evidence regarding their effects on ICI outcomes is inconsistent, in part due to confounding by indication and immortal time bias.
