“…In particular the one-sensor-mix even ensures a sensor reduction, with a negligible loss of performance. The papers by Poussot-Vassal et al 78,79 are concerned with the presentation of a robust semi-active suspension control design using a LPV approach. More specifically, the proposed semi-active suspension control strategy is designed so that it minimizes the H ∞ performance criteria while guaranteeing the limitations of the semi-active damper (i.e.…”

The real “golden age” of electronic suspension can be probably located in the 1980s; during that decade the exceptional potential of replacing a traditional spring-damper system with a fully fledged electronically controllable fast-reacting hydraulic actuator was demonstrated. High costs, significant power absorption, bulky and unreliable hydraulic systems, and uncertain management of the safety issues: the fatal attraction for fully active electronic suspensions lasted only a few years. In the second half of the 1990s, a new trend emerged: it became increasingly clear that the best compromise of cost (component cost, weight, electronics and sensors, power consumption, etc.) and performance (comfort, handling, safety) was to be found in the technology of electronically controllable suspensions: the variable-damping suspension or, in brief, the semi-active suspension. After a decade this technology is still highly promising and attractive: it has been introduced in the mass-market production of cars; it is entering the motorcycle market; a lot of special vehicles or niche applications are considering this technology; many new variable-damping technologies are being developed. Semi-active suspensions are expected to play an even more important role in the emerging trend of electric vehicles with in-wheel motors: in such a vehicle architecture the role of suspension damping is more crucial, and semi-active suspensions can significantly contribute to reduce the negative effects of the large unsprung mass. As in many other electronically controlled systems, the actuator is not “smart itself”: it simply inherits the smartness (or dumbness) of its control algorithm designer. The key of semi-active suspensions is in the algorithm. For the discussed reasons, this paper briefly reviews the basic theoretical concepts for variable-damping shock absorber technologies and the available control algorithms.

“…For example, the paper (Droździel and Wrona, 2018) notes that the road accidents are caused less by the technical malfunctions and the main causes of accidents are non-compliance with traffic rules, low qualifications of drivers, non-compliance with the work and rest periods of drivers. Nevertheless, the problem of increasing reliability does not cease to be relevant (Mohd and Srivastava, 2021;Poussot-Vassal et al, 2008), especially when operating machines in extreme conditions, which include low temperatures, among others. When the temperature decreases, the properties of fuels and lubricants, technical liquids, rubber, plastics and metals change, as well as the processes of fuel atomization and combustion in the internal combustion engine (Zöldy, 2021).…”

The use of modern materials and technical fluids allows you to operate cars at negative temperatures, but in some regions of the world (for example, in Siberia), the ambient air temperature can fall below 243 K for several weeks or even months. The operation of trucks at such a temperature refers to extreme conditions that force the special preparation of equipment. This preparation consists not only of special maintenance, but also of carrying out some activities that are carried out immediately before starting the engine and driving. The essence of these measures is, among other things, the thermal preparation of the components and assemblies of the vehicle before departure.This work is devoted to the thermal preparation of truck shock absorbers. It is revealed that the use of oils, the kinematic viscosity of which significantly depends on the ambient temperature, is a limiting factor in the winter operation of shock absorbers. The simulation of the operation of electric flexible heaters for shock absorbers in the SolidWorks Flow Simulation environment was carried out and the preheating efficiency was evaluated. It is established that the temperature distribution of the shock absorber fluid during heating of two-pipe shock absorbers occurs unevenly, but despite this, preheating significantly improves the characteristics of shock absorbers and contributes to the safe and long-lasting operation of trucks.

“…In [4], the authors compare the performance of passive suspension (vehicle dampers) with two types of active suspension based on a Linear Matrix Inequalities (LMI) controller and a quasi-Linear Parameter Varying (qLPV) controller together with the application of H 2 /H ∞ norms, finding the Pareto optimal solution for mixed norms used. Simulations were performed on a non-linear half-vehicle model (single vehicle axis).…”

The aim of this study was to analyze the dynamics of a multidimensional object based on the Pareto curve for the Linear Matrix Inequalities (LMI) controller. The study was carried out based on an available “Blue Lady” training vessel model controller with the use of a MATLAB and Simulink simulation package. Research was focused on optimising both the energy to be used when manoeuvring and the ship’s dynamics. Analysis was combined with the application of H2/H∞ norms finding the Pareto optimal solution for mixed norms used at the γ∞ parameter. Observations for a multidimensional ship model proved that it is possible to optimize the system, using principles of the Pareto curve, to reduce energy consumption in steering-propulsion systems while performing precise manoeuvres in ports correctly. Parameter values, received from observations of operation of individual steering-propulsion systems, proved to be reasonable.
