Wire of the brake pedal is not directly connected to the hydraulic environment in the braking By-wire system so the driver has no direct pedal feel. Then pedal simulator is an important part in the brake-by-wire system. A pedal force simulator was designed based on the traditional brake pedal curve of pedal force and pedal travel, AMESim and Matlab / Simulink were used as a platform to build simulation models and control algorithms. The simulation results show that the pedal stroke simulator and the control strategy meet the performance requirements of traditional braking system. It can be used in brake by wire system.

This paper discusses a low cost solution to teaching controls in the laboratory through the use of a novel balance beam. The balance beam provides a vehicle to study many aspects of both control implementation and control algorithms. Due to the complexity of the system, a full semester of laboratory exercises is provided for even advanced students. The flexibility of the system provides challenging exercises for different levels of education. A low overall cost translates to accessibility to more schools. The ability to achieve good tracking performance with a simple cascaded loop controller makes this an ideal tool for teaching controls in a laboratory setting.

Military Scenario Definition Language (MSDL) is intended to provide a standard mechanism for loading Military Scenarios independent of the applications. Some customized scenario specifications lack scalability and interoperability with Command and Control (C2) applications. And how to integrate MSDL with simulation models still needs further implementation. This paper extended and modified MSDL to propose a feasible simulation scenario specification based on our existed CGF (Computer Generated Force) model system. A CGF-SDP (Scenario Development tool) was also developed to facilitate generating course of action (COA) of a military scenario graphically based on a GIS system. A simulation scenario was generated by this editor and it was effectively used in a combat simulation system’s execution process.

In order to recycle regenerative braking energy, we built the PHEV regenerative braking test platform with model design concept, based on the parallel hybrid structure. We proposed a regenerative braking control strategy under parallel braking force distribution, and established the mathematical models for main elements of the platform. In order to confirm the performance and the operational reliability of the platform, simulation models of the regenerative braking system were built in MATLAB/Simulink by combining the test data with mathematic models. We chose universal NEDC drive cycles for simulation, and the results indicated that the regenerative braking energy was effectively recycled. The structure and control strategy of regenerative braking test platform was proved to be rational.

The current trend of electrification in modern aircraft has driven a need to design and control onboard power systems that are capable of meeting strict performance requirements while maximizing overall system efficiency. Model-based control provides the opportunity to meet the increased demands on system performance, but the development of a suitable model can be a difficult and time-consuming task. Due to the strong coupling between systems, control-oriented models should capture the underlying physical behavior regardless of energy domain or time-scale. This paper seeks to simplify the process of identifying a suitable control-oriented model by defining a scalable and broadly applicable approach to generating graph-based models of thermal, electrical, and turbomachinery aircraft components and systems. Subsequently, the process of assembling component graphs into a dynamical system graph that integrates multiple energy domains is shown. A sample electrical and thermal management system is used to demonstrate the capability of a graph model at matching the complex dynamics exhibited by nonlinear and empirically based simulation models.

Submarine inspections and surveys require underwater vehicles to operate in deep waters efficiently, safely and reliably. Autonomous Underwater Vehicles employing advanced navigation and control systems present several advantages. Robust control algorithms and novel improvements in positioning and navigation are needed to optimize underwater operations. This paper proposes a new general formulation of this problem together with a basic approach for the management of deep underwater operations. This approach considers the field of view and the operational requirements as a fundamental input in the development of the trajectory in the autonomous guidance system. The constraints and involved variables are also defined, providing more accurate modelling compared with traditional formulations of the positioning system. Different case studies are presented based on commercial underwater cameras/sonars, analysing the influence of the main variables in the measurement process to obtain optimal resolution results. The application of this approach in autonomous underwater operations ensures suitable data acquisition processes according to the payload installed onboard.

This article discusses the work that resulted in the development of two battery-powered self-propelled electric mining machines intended for operation in the conditions of a Polish copper ore mine. Currently, the global mining industry is seeing a growing interest in battery-powered electric machines, which are replacing solutions powered by internal combustion engines. The cooperation of Mine Master, Łukasiewicz Research Network—Institute of Innovative Technologies EMAG and AGH University of Science and Technology allowed carrying out a number of works that resulted in the production of two completely new machines. In order to develop the requirements and assumptions for the designed battery-powered propulsion systems, underground tests of the existing combustion machines were carried out. Based on the results of these tests, power supply systems and control algorithms were developed and verified in a virtual environment. Next, a laboratory test stand for validating power supply systems and control algorithms was developed and constructed. The tests were aimed at checking all possible situations in which the battery gets discharged as a result of the machine’s ride or operation and when it is charged from the mine’s mains or with energy recovered during braking. Simulations of undesirable situations, such as fluctuations in the supply voltage or charging power limitation, were also carried out at the test stand. Positive test results were obtained. Finally, the power supply systems along with control algorithms were implemented and tested in the produced battery-powered machines during operational trials. The power systems and control algorithms are universal enough to be implemented in two different types of machines. Both machines were specially designed to substitute diesel machines in the conditions of a Polish ore mine. They are the lowest underground battery-powered drilling and bolting rigs with onboard chargers. The machines can also be charged by external fast battery chargers.
