Nonlinear dynamic analysis and robust controller design for Francis hydraulic turbine regulating system with a straight-tube surge tank
TL;DR: In this paper, a mathematical model of hydraulic turbine regulating system with a straight-tube surge tank based on a few state-space equations is introduced to study the dynamic behaviors of the HTRS system, where the existence of possible unstable oscillations of this model is extensively and presented in the forms of the bifurcation diagram, time waveform plot, phase trajectories, and power spectrum.

Control of tractor-trailer wheeled robots considering self-collision effect and actuator saturation limitations
TL;DR: The developed controllers produce control signals in the feasible bounds of the actuators and also avoid self-collision systematically, and trajectory tracking and obstacle avoidance problems are solved simultaneously using NMPC capability.

The optimum matching control and dynamic analysis for air suspension of multi-axle vehicles with anti-roll hydraulically interconnected system
TL;DR: Dynamic simulation analysis shows that D23 and D123 have great application value as the optimum strategy considering the engineering cost and anti-roll capacity, and a fuzzy controller is proposed for the problem of insufficient roll resistance of D23.

Vehicle lateral motion regulation under unreliable communication links based on robust H ∞ output-feedback control schema
TL;DR: In this paper, a robust control schema for vehicle lateral motion regulation under unreliable communication links via controller area network (CAN) is presented, where the communication links between the system plant and the controller are assumed to be imperfect and therefore the data packet dropouts occur frequently.
