Practical examples of systems with heterogeneous timing requirements include the embedded real-time control and decisionmaking systems used in aerospace, automotive, and telecommunication applications. It is attractive to construct such systems as digital networks with inherent heterogeneous timing conditions. In these hets (short for heterogeneously timed nets), computational elements interact...

This paper describes a systematic procedure to exponentially stabilize relative equilibria of mechanical systems. We review the notion of relative equilibria and their stability in a Riemannian geometry context. Potential shaping and damping control are employed to obtain full exponential stabilization of the desired trajectory. Two necessary conditions are that the effective potential be posit...

In this paper one solution for teaching skills to construct the control object frequency characteristics method is described. Student’s mistakes are discovered and classified. Based on signal-parametric approach to fault diagnosis in dynamic systems mathematical diagnostic models which allow detecting mistake classes by comparing student calculated results and system calculated results are crea...

This paper gives an account of various challenges that are faced in the design and development of complex control systems and software, within the automotive and aerospace domains, in particular, which are highly relevant to the incorporation of active mechanisms for dynamic systems. It also analyses what new recent advances are helping some of these being overcome in the research and engineeri...
