Nonlinear Robust Tracking Control of an Underwater Vehicle-Manipulator System

This paper develops an improved robust multi-surface sliding mode controller for a complicated five degrees of freedom Underwater Vehicle-Manipulator System with floating base. The proposed method combines the robust controller with some corrective terms to decrease the tracking error in transient and steady state. This approach improves the performance of the nonlinear dynamic control scheme a...

ASSESSING THE EFFECT OF BLOCKAGE OF DIRT ON ENGINE RADIATOR IN THE ENGINE COOLING SYSTEM

This thesis looked at the effect of clay and silt soil blocking the heat transfer area of the radiator and its effect on the engine coolant through the conduct of experiments and a mathematical model developed. The results indicated that the percentage area covered resulted in a proportional increase of the inlet and outlet temperatures of the coolant in the radiator. The mathematically mode...

FPGA-Based Cooling Fan Control System for Automobile Engine

In this paper FPGA is used as the master chip to design the new fourphase sensorless BLDC(brushless direct current) motor control system of automobile engine cooling fan. The design uses BEMF zero-crossing detection algorithm and the hardware modular design approach, while the open-loop circuit adopted to raise the frequency and voltage and the digital phase-shift circuit based on FIPS algorith...

Robust Nonlinear Control Design with Application to a Marine Cooling System

In this paper we consider design of control laws for a marine cooling system with flow dependent delays by use of principles from feedback linearization. To deal with model uncertainties and delay mismatches, a robust linear H∞ controller is designed for the feedback linearized system. In this context, we apply a bilinear transformation to obtain a well-posed H∞ problem. Robustness of performan...
