1. FUZZY SLIDING-MODE TEMPERATURE-CONTROL SYSTEM FOR SOAKING AND GERMINATION OF RICE SEEDS
ABSTRACT The soaking and germination process of rice seeds is the starting point in rice cultivation in cold regions and has a significant effect on grain yield. Efficient techniques for controlling the water temperature in the seed tank are required to enhance germination quality. This paper introduces a fuzzy theory for designing a fuzzy logic-based slidin

3. Integrated Guidance and Control of Multiple Interceptor Missiles Based on Improved Distributed Cooperative Control Strategy
ABSTRACT In this study, an improved cooperative integrated guidance and control (IGC) design method is proposed based on distributed networks to address the guidance and control problem of multiple interceptor missiles. An IGC model for a leading interceptor is constructed based on the relative kinematic relations between missiles and a target and the kinema

4. Research on Sliding Mode Method about Three-Dimensional Integrated Guidance and Control for Air-to-Ground Missile
ABSTRACT Based on adaptive sliding mode-control and back-stepping design method, an integrated guidance and control method with less calculation is proposed, which is designed for air-to-ground missile during the terminal course in three-dimensional space. The model of the control system with nonlinear and coupling is simplified, then the integrated guidance

5. Adaptive Fuzzy Sliding-Mode Control of Wheel Slide Protection Device for ER24PC Locomotive
Abstract Wheel Slide Protection Devices (WSPD) are employed in railway vehicles to maximize the average of the possible frictional braking force, which is a nonlinear function of the slip ratio of the wheel sets. In this paper, to control the WSPD, a low-order model is presented and un-modeled dynamics are considered as uncertainties. Due to the nonlinear dy

6. Control of input delayed pneumatic vibration isolation table using adaptive fuzzy sliding mode
AbstractPneumatic isolators are promising candidates for increasing the quality of accurate instruments. For this purpose, higher performance of such isolators is a prerequisite. In particular, the time-delay due to the air transmission is an inherent issue with pneumatic systems, which needs to be overcome using modern control methods. In this paper an adap

7. Controle por modo deslizante para sistemas não-lineares com atraso. / Sliding mode control for nonlinear systems with time delay.
Nesta Dissertação são propostos dois esquemas de controle para sistemas não-lineares com atraso. No primeiro, o objetivo é controlar uma classe de sistemas incertos multivariáveis, de grau relativo unitário, com perturbações não-lineares descasadas dependentes do estado, e com atraso incerto e variante no tempo em relação ao estado. No segundo, d

8. Controlador nebuloso por modos deslizantes adaptativo
In this work, an Adaptive Sliding Neurofuzzy Controller was proposed and its parameters had been established and well characterized. In this way, some concepts of the theories of neurofuzzy networks, sliding mode control and adaptive control had been treated. The considered controller presents only three inference rules and a low computational effort. It was

9. Controle ótimo por modos deslizantes via função penalidade / Optimal sliding mode control approach penalty function
Este trabalho aborda o problema de controle ótimo por modos deslizantes via função penalidade para sistemas de tempo discreto. Para resolver este problema será desenvolvido uma estrutura matricial alternativa baseada no problema de mínimos quadrados ponderados e funções penalidade. A partir desta nova formulação é possível obter a lei de controle

11. Controle por modos deslizantes aplicado a sistema de posicionamento dinâmico. / Sliding mode control applied to dynamic positioning systems.
This paper presents the application of the robust and nonlinear sliding mode control theory to the dynamic positioning systems for floating vessel, with experimental validation. The objective of the control system designed is to keep the vessel next a specific position (set-point) or follow a pre-defined trajectory (pathfollowing) through the action of prope

12. Projeto e construção de um robô cartesiano com acionamento pneumático
O presente trabalho trata do projeto, construção e análise de desempenho de um robô pneumático com três graus de liberdade. Foi fundamentado no trabalho de Frasson (2007) com alterações na escolha de componentes que permitissem a redução de custos. Tem como objetivo verificar se um robô comandado por válvulas solenóide rápidas, e controlado pel
