In this paper, a highly non-linear model of an autonomous underwater vehicle (AUV) with six
degrees-of-freedom is linearized to yaw (horizontal) and pitch (vertical) planes under …

Quadrotor helicopter is an unstable system subject to matched and mismatched
disturbances. To stabilize the quadrotor dynamics in the presence of these disturbances, the …

A new combination of fractional order (FO) nonlinear control and sliding mode observer
(SMO) for blood glucose regulation in type 1 diabetes mellitus is proposed in this paper. An …

Sliding mode control (SMC) is emerged as a powerful robust controller for the process
control application. However, it does not posses robustness properties during reaching …

Many multi-variable systems are modeled as two-input-two-output (TITO) systems with time
delay. Such systems are difficult to control due to interaction among the variables and time …

Multiple input multiple output systems posses interaction among the variables and hence
are difficult to control. In addition, if these systems have slow and non-linear dynamics with …

This study proposed a State feedback controller (SFC) with a Disturbance observer (DO) for
a flexible joint robotic arm under disturbances. The dynamic model of flexible joint robotic …

This paper presents a state and perturbation observer based state feedback control for
active suspension systems. The state and perturbation observer estimates the lumped …

Estimation of the exogenous input is an important topic in various applications. Unknown
inputs can dramatically degrade the estimation performance in systems with unknown but …

This paper deals with a fault detection approach based on an observer, applied to the
handwriting biological process. This process is characterized by a linear model generating …
