This paper is centered on the guidance systems used to increase the autonomy of unmanned surface vehicles (USVs). The new Robust Reactive Static Obstacle Avoidance System (RRSOAS) has been specifically designed for USVs. This algorithm is easily applicable, since previous knowledge of the USV mathematical model and its controllers is not needed. In...

This work is focused on reactive Static Obstacle Avoidance (SOA) methods used to increase the autonomy of Unmanned Surface Vehicles (USVs). Currently, there are multiple approaches to avoid obstacles, which can be applied to different types of USV. In order to assist in the choice of the SOA method for a particular vessel and to accelerate the pret...

This work is located in a growing sector within the field of renewable energies, wave energy converters (WECs). Specifically, it focuses on one of the point absorber waves (PAWs) of the hybrid platform W2POWER.With the aim of maximizing the mechanical power extracted from the waves by these WECs and reducing their mechanical fatigue, the design of...

The ship roll stabilization by active anti-heeling tanks operated by pressurized air is considered in this book. Assuming that there exist uncertain parameters and uncertain external perturbation in the ship roll model, a backstepping structure with robust control algorithm for ship roll stabilization system is designed . A roll equation consisting...

The search for alternatives to traditional energy sources is an important issue nowadays. Renewable energies are difficult to use because, among other factors, the uncertainty about their availability. One option to address this problem are hybrid systems, where different primary energy sources and storage systems are used. A hybrid system contains...

The aim of this paper is to present several applications used in Microcontrollers practical sessions of the Degree in Radioelectronics Engineering of the University of Cadiz. Block diagrams prove to be a suitable visual tool in programming especially in academic degrees where computer programming is not provided with a relevant specific weight. Thi...

This paper presents the control of the list angle of a ship in still water based on the utilisation of anti-heeling tanks oper-ated by pressurized air. The proposed and practical objective attempts to regulate the list angle to a prescribed value, nor-mally zero, during the loading process of a container ship. A nonlinear adaptive controller based...

The production of hot water for use in a Hospital can use solar energy as a main energy source. The hot water production system can also use fossil energy in cases were the demand is too high to be satisfied with solar power. The resulting system is hybrid and its control poses some problems. In this paper the work in progress towards the control o...

In this paper we propose a control system design methodology which has two main objectives: the first one is to achieve control system specifications for a local H∞ controller designed for a given operation condition, and the second objective is to provide a procedure for bumpless transfer (BLT) when the controller is switched to another one, due t...

In this work we use computer simulations to test a method for controlling heart rhythm behavior based on the electrocardiogram (ECG) signal tracking. The proposed control algorithm is based on two parameters, the controller proportional gain and the norm of tracking error signal. The objective is to take out the heart rhythm dynamics from a non des...

A method for controller design and switching controller without bump effect has been proposed for a marine propulsion system with diesel engine used as propeller prime-mover. Due to different regimens operation of ship propulsion, it is common practice to design more than one linear controller, each at a different operating point, and to switch bet...

In this work a computer based environment for symbolic calculation applied to nonlinear L 2 control is described. A very practical design and analysis methodology for nonlinear H ∞ control is presented. Starting from a model of the plant in affine form, and a state feedback controller (or state estimated feedback controller), a design procedure is...

In this work a design procedure for course-changing control and path tracking control is presented, which is based on nonlinear L2 control theory. The proposed method uses a nonlinear model of the ship and obtains a non-linear suboptimal H∞ controller (state feedback version or state estimated approach with a non-linear observer). A symbolic comput...

An automatic procedure for H-infinity regulator tuning is proposed. Design parameters are calculated based on a few parameters of a simple plant model, which are obtained by an identification method. With this approach adequate performance and robustness are guaranteed, and it is available an automaticH1 design method for the user. A fine-tuning of...

In this work we present a study carried out for a ship of Ferry type. An H∞ regulator is developed to keep a fixed course of the ship, and another H∞ controller is designed for course changing operation. Both designs have into account the physical limitations of the rudder servosystem. and uncertainties in ship dynamics. The objective of the contro...
