This paper presents an LMI based fixed-order controller design for quarter car active suspension system in order to ensure ℋ∞ performance and the stability in the predefined D-Region. The simulation results and dynamic response of the real system show the effectiveness of the proposed method over improvements on ride comfort. The proposed low-order controller is compared with full-order one in simulation...
In this paper, the optimal fuel impulsive time-fixed rendezvous problem is considered. Under some simplifying assumptions, this problem may be recast as a non convex polynomial optimization problem. A numerical solving algorithm using a convex relaxation based on sum-of-squares representation of positive polynomials is proposed. Numerical results are evaluated on the PRISMA technology in-orbit formation...
The design problem of mixed L2, H2 gain scheduling nonlinear state feedback controller for Linear Parameter Varying (LPV) systems subjected to actuator saturations and L2 bounded disturbances is considered. First, a new formulation of H2 controllers has been presented based on the homogeneous polynomial parameter dependent (HPPD) representation. Then a systematic procedure to generate a sequence of...
This paper addresses the design method for robust PID like controllers which guarantee the quadratic stability, performance in terms of H2 and Hinfin specifications, pole locations and maximum output control. The approach is based on the transformation of the PID controller design problem to that of state feedback controller design thereby the convex optimization approaches can be adapted. Real time...
A novel, improved adaptive control methodology equipped with variable structure controller which utilizes the disturbance estimate is proposed for the control of robot manipulators. The main property of the method is that, it does not requires for any information about the disturbances that act on the system such as bounds or limits. On the other hand, the proposed control method eliminates the drawbacks...
