The paper proposes a stability analysis method based on the application of the center manifold theory belonging to the state-space methods to the stability analysis of fiizzy control systems. The methods considers a linearized mathematical model of the second order nonlinear plant, and its only constraint is in the smooth character of the right-hand term of… (More)
Synthesis of static anti-windup compensators is considered. LMI conditions are established for stability and performance analysis of the closed loop system. The performance criterion describes the servo problem for the resulting closed-loop piecewise linear system. The synthesis of the anti-windup compensators will be given by some bilinear matrix… (More)
The servo problem for a wide class of nonlinear system is considered. A quantitative bound on system trajectories is derived. For piecewise linear systems the bound is shown to be computable in terms of linear matrix inequalities.
We consider the problem of rear axle regenerative braking maximization in hybrid vehicles. We focus on cornering maneuvers on low friction surfaces, where excessive braking at the rear axle might induce vehicle instability. We present and compare two predictive control approaches, where the objective is maximizing the regenerative braking and distributing… (More)
One of the major benefits of driving vehicles in controlled, close formations such as platoons is that of reduced air drag. However, this will set hard performance requirements on the system actuators, sensors and controllers of each vehicle. This paper analyzes the effects of fundamental limitations on the longitudinal and lateral control performance of a… (More)
The notion of vehicles moving in platoons is of considerable interest when seeking to decrease traffic congestion and gas consumption. This usually means automated operation in longitudinal and possibly lateral direction. This report focuses on the lateral dynamics and control of a vehicle platoon following a leader in the lateral direction. A thorough… (More)
A novel method for voltage stability control in power networks is considered. Dynamic compensation of the voltage reference is used togheter with a VIP (voltage instability predictor) based load shedding. Simulation results will be presented.
PID controller design is considered where optimal controller parameters are found with constraint on maximum sensitivity and robustness with regard to cone bounded static nonlinearity acting on the plant.
