2. STATE ESTIMATION AND TRAJECTORY TRACKING CONTROL FOR A NONLINEAR AND MULTIVARIABLE BIOETHANOL PRODUCTION SYSTEM
ABSTRACT In this paper a controller is proposed based on linear algebra for a fed-batch bioethanol production process. It involves finding feed rate profiles (control actions obtained as a solution of a linear equations system) in order to make the system follow predefined concentration profiles. A neural network states estimation is designed in order to kno

4. Robust Optimal Adaptive Trajectory Tracking Control of Quadrotor Helicopter
Abstract This paper focuses on robust optimal adaptive control strategy to deal with tracking problem of a quadrotor unmanned aerial vehicle (UAV) in presence of parametric uncertainties, actuator amplitude constraints, and unknown time-varying external disturbances. First, Lyapunov-based indirect adaptive controller optimized by particle swarm optimization

5. A Model Predictive Guidance Strategy for a Multirotor Aerial Vehicle
ABSTRACT: The present study faces the problem of safely controlling the position trajectory of a multirotor aerial vehicle subjected to a conic constraint on the total thrust vector and a linear convex constraint on the position vector. The problem is solved using a linear state-space model predictive control strategy, whose optimization is made handy by rep

6. The Control of Asymmetric Rolling Missiles Based on Improved Trajectory Linearization Control Method
ABSTRACT According to motion characteristic of an asymmetric rolling missile with damage fin, a three-channel controlled model is established. The controller which is used to realize non-linear tracking and decoupling control of the roll and angle motion is introduced based on an improved trajectory linearization control method. The improved method is compos

7. Tracking control of a planar five-link bipedal walking system with point contact, considering self-impact joint constraint by adaptive neural network method
AbstractIn order to achieve the practical characteristics of natural bipedal walking, a key feature is to realize "the straight knee state of walking" during stance and swing motions. Considering a straight knee necessitates that the shank link of each leg not to undergo the rotation angles which are greater than that of the thigh link. For this purpose, var

9. An Approach to Outlier Detection and Smoothing Applied to a Trajectography Radar Data
ABSTRACT: The tracking of aerospace engines is reasonably achieved through a trajectography radar system that generally yields a disperse cloud of samples on tridimensional space, which roughly describes the engine trajectory. It is proposed an approach on cleaning radar data to yield a well-behaved and smooth output curve that could be used as basis for ins

10. Planejamento periódico de trajetórias de sistemas afins sem arrasto em grupos de Lie compactos / Periodic motion planning of trajectories for control-affine driftless systems in compact Lie groups
We treat the periodic motion planning problem: given a periodic trajectory of a control-affine driftless system in a compact and connected Lie group G and an initial condition in G, find another trajectory of the same system satisfying the initial condition given and that asymptotically tracks the periodic trajectory. We solve this problem locally (for initi

12. Planejamento de trajetórias robóticas utilizando B-splines / Robotics trajectory planning using B-spline
Robot trajectory planning is the specification of the path the terminal element of the robot should move to accomplish a certain task. The trajectory planning can be done in the task domain or in the joints domain. For any domains that the trajectories are planned, it should be defined by a curve fitting function, such as approximation or interpolation of th
