About string stability of a vehicle chain with unidirectional controller
Arash Farnam, Alain Sarlette
This paper deals with the problem of string stability in a chain of acceleration-controlled vehicles. It is known that string stability cannot be achieved, with any linear controll…
About strong string stability of a vehicle chain with time-headway control
Arash Farnam, Alain Sarlette
This paper deals with the problem of string stability in a chain of acceleration-controlled vehicles, i.e. how input disturbances affect the distributed system for very long chains…
Towards a comprehensive impossibility result for string stability
Arash Farnam, Alain Sarlette
We provide a comprehensive impossibility result towards achieving string stability, i.e. keeping local relative errors in check with local controllers independently of the size of…
Lifting Markov Chains To Mix Faster: Limits and Opportunities
Simon Apers, Francesco Ticozzi, Alain Sarlette
Lifted Markov chains are Markov chains on graphs with added local "memory" and can be used to mix towards a target distribution faster than their memoryless counterparts. Upper and…
Integral control on nonlinear spaces: two extensions
Zhifei Zhang, Zhihao Ling, Alain Sarlette
This paper applies the recently developed framework for integral control on nonlinear spaces to two non-standard cases. First, we show that the property of perfect target stabiliza…
String Stability towards Leader thanks to Asymmetric Bidirectional Controller
Arash Farnam, Alain Sarlette
This paper deals with the problem of string stability of interconnected systems with double-integrator open loop dynamics (e.g.~acceleration-controlled vehicles). We analyze an asy…
