Adaptive Attitude Control of a Rigid Body With Input and Output Quantization

Adaptive Input-Output Linearization Control of pH Processes

pH control is a challenging problem due to its highly nonlinear nature. In this paper the performances of two different adaptive global linearizing controllers (GLC) are compared. Least squares technique has been used for identifying the titration curve. The first controller is a standard GLC based on material balances of each species. For implementation of this controller a nonlinear state...

Optimal Attitude Control of a Rigid Body using Geometrically

An efficient and accurate computational approach is proposed for optimal attitude control of a rigid body. The problem is formulated directly as a discrete time optimization problem using a Lie group variational integrator. Discrete necessary conditions for optimality are derived, and an efficient computational approach is proposed to solve the resulting two point boundary value problem. The us...

Smooth Adaptive Finite Time Attitude Tracking Control of Rigid Spacecraft

This paper investigates two chattering-free finite-time controllers for the rigid spacecraft attitude tracking control problem considering modeling uncertainty and external disturbance. First, the basic controller is designed utilizing integral terminal sliding mode surface (ITSMS) with prior knowledge of the total system uncertainty consisting of modeling uncertainty and external disturbance. ...
