Auto-tuning of cascade control systems

ISA Transactions, 2003
In this paper, a novel auto-tuning method for a cascade control system is proposed. By employing a simple relay feedback test, both inner and outer loop model parameters can be simultaneously identified. Consequently, well-established proportional-integral-derivative (PID) tuning rules can be applied to tune both loops.

A cascade control for Sander automation system

2015 IEEE International Conference on Automation Science and Engineering (CASE), 2015
Hydraulic fracturing is one of the key technologies that are currently used for shale oil and gas production. Sander is the equipment that delivers various types of sand with desired sand rate demand and dumps the sand to the blender's sand hopper for hydraulic fracturing.

A Novel Control for Dual Cascaded Inverters

2007 IEEE Industry Applications Annual Meeting, 2007
In this paper, a high performance modulation technique for dual inverter with separate dc sources feeding open-end winding induction motors is proposed. It is based on a optimization algorithm, which carries out the suitable modulation pattern for the dual inverter in order to minimize power losses.

Robust control of cascaded nonlinear systems

Proceedings. 2000 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2000) (Cat. No.00CH37113), 2002
Robust control is designed for nonlinear uncertain systems, which can be decomposed into two cascaded subsystems, that is, a series connection of two nonlinear subsystems. For such a system, a recursive design is used to include a second subsystem in robust control. The recursive design procedure is constructive and contains two steps.

A Cascade Feedback Control Approach for Hypnosis

Annals of Biomedical Engineering, 2005
This article studies the problem of controlling the drug administration during an anesthesia process, where muscle relaxation, analgesia, and hypnosis are regulated by means of monitored administration of specific drugs. On the basis of a seventh-order nonlinear pharmacokinetic-pharmacodynamic representation of the hypnosis process dynamics, a cascade (

Cascade Control Systems

1981
The design of an optimal state controller involves the feedback of all the state variables of the process. If not all state variables can be measured, but for example only one state variable between the process input and output, then improvements can be obtained for single loop systems using for example parameter optimized controllers, by assuming this

Variable control scheme in the cascade processes

Expert Systems with Applications, 2010
The article considers the variables process control scheme for cascade processes. We construct variable sample sizes and sampling intervals (VSSI) control charts to effectively monitor the input variable and the output variable produced by a cascade process. The performance of the proposed VSSI control charts is measured by the adjusted average time to

Cascaded Control of Multi-agent Systems

2004
Intelligent software agents are an important enabling technology for the next generation of distributed information systems. As agent-based applications spread and enter the realm of survivable and embedded systems, the issues of control become prominent in the development of agent architectures.
