“…As described in [6], and as shown in Figure 3, the classical decentralised control (based on local per vehicle sensors) attempts to control the vehicle lateral and roll dynamics in two single input single output loops, in which the effective cant deficiency (ECD) and measured vehicle body lateral acceleration are used for tilt control and the lateral actuator (ride quality remedial action) control, respectively. Lateral actuator control loop is the inner loop and designed firstly because it is a high-bandwidth loop that responds to the high-frequency track irregularity (2-10 Hz), being faster than the tilting action (for which the bandwidth is below 1 Hz).…”

“…The skyhook damping control [13] is employed for the lateral actuator while proportional-integral-derivative (PID) control is used for the tilt control. The detailed simulation results were discussed in [6], but a short summary is presented here. As shown in Figure 8, Complete figure see the published paper on T&F EBD control is close to conventional precedence tilting (PT) control, [4] hence quite close to the so-called 'ideal tilt' action.…”

“…Moreover, tilting trains run at a higher speed on the same rail infrastructure compared to non-tilting trains, which deteriorates ride-quality performance on straight track and introduces a trade-off, for the tilting controller, between curving performance and straight track ride quality. In this context, the addition of a secondary lateral actuator and its integration with tilt control are largely discussed in [6]. The straight track ride quality and tilt performance are significantly improved with the lateral-tilt integrated active suspension configuration.…”

The interaction between the railway vehicle body roll and lateral dynamics substantially influences the tilting system performance in high-speed tilting trains, which results in a potential poor ride comfort and high risk of motion sickness. Integrating active lateral secondary suspension into the tilting control system is one of the solutions to provide a remedy to roll-lateral interaction. It improves the design trade-off for the local tilt control (based only upon local vehicle measurements) between straight track ride comfort and curving performance. Advanced system state estimation technology can be applied to further enhance the system performance, i.e. by using the estimated vehicle body lateral acceleration (relative to the track) and true cant deficiency in the configuration of the tilt and lateral active suspension controllers, thus to further attenuate the system dynamics coupling. Robust H ∞ filtering is investigated in this paper aiming to offer a robust estimation (i.e. estimation in the presence of uncertainty) for the required variables, In particular, it can minimise the maximum estimation error and thus be more robust to system parametric uncertainty. Simulation results illustrate the effectiveness of the proposed schemes.
