Multi objective H∞ active anti-roll bar control for heavy vehicles

The Development of an Active Roll Control System for Heavy Vehicles

1.1. Background Studies have shown that most rollover accidents involve heavy articulated vehicles, and occur on highways [1]. Three major contributing factors to rollover accidents have been identified: (1) sudden course deviation, often in combination with heavy braking, from high initial speed; (2) excessive speed on curves; and, (3) load shift. The accidents are relatively frequent, and the...

Comparison between LQR and ANN Active Anti-Roll Control of a Single Unit Heavy Vehicle

Heavy-duty Vehicle Rollover Detection and Active Roll Control

The safety of road vehicles depends on the yaw-roll dynamics. A loss of roll stability results in a rollover accident. Mechanisms to warn against rollover threat and a rollover avoidance control methodology are crucial in designing a successful active safety warning/control system for heavy-duty commercial vehicles. A dynamic rollover metric, Time-To-Rollover (TTR), has become popular in rollov...

Dual Problem in Multi-Objective H Control

In this paper, we approach a multi-objectiveH problem with several H constraints from the Banach duality point of view. The problem is reduced to an abstract norm minimization problem, and the dual problem is derived using the classical Banach result. It completes the primal-dual pair which can be used to solve the problem numerically by finitedimensional approximations. While the approximation...

Multi-objective H ∞ control for vehicle active suspension systems with random actuator delay

This paper is concerned with the problem of multi-objective H∞ control for vehicle active suspension systems with random actuator delay, which can be represented by signal probability distribution. First, the dynamical equations of a quarter-car suspension model are established for the control design purpose. Secondly, when taking into account vehicle performance requirements, namely, ride comf...
