The proposed article deals with uncertain description of permanent-magnet DC motor Maxon RE 35 via parametric uncertainty and H-infinity controller design. There was analyzed influence of uncertainties of the particular motor parameters on the model behavior. Consequently there was designed an H-infinity controller via Matlab functions. The behavior of the obtained controller was analyzed on the step responses and course tracking of the closed loop with the nominal system and the system with perturbed parameters. and Obsahuje seznam literatury
This paper is concentrated on a reactive sensor - based omnidirectional motion mode in in-door robot surrounding. A high accuracy dead - reckogning and obstacle avoidance of the robot is acquired. The method supposes the use of odometer robot means. The model assumes that the wheel distance measurement errors are random zero means white noise. Algorithms developed will be implemented within a generic SW architecture and used on ‘OMR III‘ experimental robot. and Obsahuje seznam literatury
The active magnetic bearing control through analytically designed linear PD regulator, with parallel nonlinear compensation represented by automatic approximator is described in this contribution. Coefficient (parameter) values come from actions of Continuous Action Reinforcement Learning Automata (CARLAs). Modified algorithm for automata implementation is used which continuously updates learning parameters according to former learning process. The goal of this on-line training is formulated as achievement of minimum mean square of control error. Described concept of control is proved by simulation study. It is shown that the significant improvement of whole system behavior can be achieved. and Obsahuje seznam literatury
