To facilitate the damping matching of dampers for vehicle passive suspensions, this paper proposes an analytical matching method of the optimal piecewise linear damping characteristics curve. Based on the vehicle vibration model, taking the suspension dynamic deflection as the constraint, by the vibration acceleration and the wheel dynamic load, an objective function about the relative damping ...

This paper describes a new technique called piecewise linear reasoning (PLR) for analyzing dynamic systems describable by finite sets of ordinary differential equs tions. Current qualitative reasoning programs derive the abstract behavior of a system by simulating handcrafted “qualitative” versions of the differential equations that characterize it and summarizing the results. PLR infers more d...

This paper describes a systematic technique for obtaining controllers for Nonlinear Systems using a Continuous Piecewise Linear Approximation (CPWL) of the given Nonlinear vector field. The method proposes the use of a CPWL approximation of the Nonlinear System and then a theory is developed to show that the stabilization of the CPWL aproximation ODE yields stability for the Nonlinear ODE. An e...

This article deals with the identification of the so called hinging hyperplane models. This type of non-linear black-box models is relatively new, and its identification is not thoroughly examined and discussed so far. They can be an alternative to artificial neural nets but there is a clear need for an effective identification method. This paper presents a new identification technique for that...

This article proposes a virtual sensor for piecewise linear systems based on observability analysis that is in function of a commutation law related with the system's outpu. This virtual sensor is also known as a state estimator. Besides, it presents a detector of active mode when the commutation sequences of each linear subsystem are arbitrary and unknown. For the previous, this article propos...

This paper addresses the identification of non–linear dynamic systems. A wide class of these systems can be described using non–linear time-invariant regression models, that can be approximated by means of piecewise affine prototypes with an arbitrary degree of accuracy. This work concerns the identification of piecewise affine model structure through input–output data acquired from a dynamic p...

This paper studies controllability of bimodal systems that consist of two linear dynamics on each side of a given hyperplane. We show that the controllability properties of these systems can be inferred from those of linear systems for which the inputs are constrained in a certain way. Inspired by the earlier work on constrained controllability of linear systems, we derive necessary and suffici...
