The objective of this study is to design a robust direct model reference adaptive controller (DMRAC) for a nonlinear cardiovascular model over a range of plant parameters representing a variety of physical conditions. The direct adaptive controllers used in thisd study require the plant to be almost strictly positive real (ASPR) that is, for a plant to be controlled there must exist a feedback ...

In this note, a fault-tolerant control strategy is proposed from a robust control perspective by applying the recently introduced GIMC (Generalized Internal Mode Control) architecture. This fault-tolerant control design consists of two parts: a nominal performance controller and a robustness controller, and works in such way that when a sensor failure is detected, the controller structure is re...

 Two passivity-based controllers and an input-output linearization controller for current-fed saturated induction motors are presented. Advantages and disadvantages of the controllers are discussed. Finally, experimental results obtained with one of the passivity-based controllers are presented.

In this paper, the design and implementation of adaptive speed controller for a sensorless synchronous reluctance motor (SynRM) drive system is proposed. A combination of well-known adaptive input-output feedback linearization (AIOFL) and adaptive backstepping (ABS) techniques are used for speed tracking control of SynRM. The AIOFL controller is capable of estimating motor two-axis inductances ...

This paper presents a new approach based on Youla parametrization, to retune Generalised Predictive Control (GPC) law while preserving its two degrees of freedom structure. This results in a more robust controller with improved high frequency disturbance rejection properties. The proposed strategy expresses an initial controller in a powerful form via the Youla theory, each transfer function of...

This paper focuses on a new controller design for both AC output voltage and DC voltage sides of a 3-level voltage source converter (VSC) of STATCOM based on complex transfer function. With this approach, the current regulator control with two-input two-output for the AC side of VSC can be represented by a complex transfer function with single-input single-output. In addition, the complex pole-...
