ROBUST OUTPUT FEEDBACK DISTURBANCE REJECTION CONTROL BY SIMULTANEOUSLY ESTIMATING STATE AND DISTURBANCE
This paper tackles the problem of simultaneous estimation of the state and the unknown disturbance of an MIMO disturbed system and designs the disturbance rejection controller according to the estimation information. Through a series of transformations, we can transform the original system into two ....

HIGHER-ORDER GENERALIZED INVEXITY IN CONTROL PROBLEMS
We introduce a higher-order duality (Mangasarian type and Mond-Weir type) for the control problem. Under the higher-order generalized invexity assumptions on the functions that compose the primal problems, higher-order duality results (weak duality, strong duality, and converse duality) are derived ....

EMPIRICAL MODEL FOR ESTIMATING GLOBAL SOLAR RADIATION ON HORIZONTAL SURFACES FOR SELECTED CITIES IN THE SIX GEOPOLITICAL ZONES IN NIGERIA
This study proposes a temperature-based model of monthly mean daily global solar radiation on horizontal surfaces for selected cities, representing the six geopolitical zones in Nigeria. The modelling was based on linear regression theory and was computed using monthly mean daily data set for minimu....

PARALLEL TRACKING AND MAPPING FOR CONTROLLING VTOL AIRFRAME
This work presents a vision based system for navigation on a vertical takeoff and landing unmanned aerial vehicle (UAV). This is a monocular vision based, simultaneous localization and mapping (SLAM) system, which measures the position and orientation of the camera and builds a map of the environmen....

SLAVE SYSTEM DIMENSION EXPANSION APPROACH FOR ROBUST SYNCHRONIZATION OF CHAOTIC SYSTEMS WITH UNKNOWN PHASE DIFFERENCE
A technique which increased the dimension of slave system is adopted for robust synchronization of chaotic systems with unknown phase difference. The phase difference plays a great role in variation of dynamic behavior of the coupled systems. The phase difference of the sinusoidal forcing term is al....

ON THE DYNAMICS OF THE FURUTA PENDULUM
The Furuta pendulum, or rotational inverted pendulum, is a system found in many control labs. It provides a compact yet impressive platform for control demonstrations and draws the attention of the control community as a platform for the development of nonlinear control laws. Despite the popularity ....

POLE PLACEMENT-BASED NMPC OF HAMMERSTEIN SYSTEMS AND ITS APPLICATION TO GRADE TRANSITION CONTROL OF POLYPROPYLENE
This paper presents a new nonlinear model predictive control (MPC) algorithm for Hammerstein systems subject to constraints on the state, input, and intermediate variable. Taking no account of constraints, a desired linear controller of the intermediate variable is obtained by applying pole placemen....
