It is well-known that the accurate measurement of input voltage and current, as feedforward feedback terms, plays a crucial role in nonlinear controller design for power factor compensation an AC-DC boost converter. This paper addresses problem simultaneous estimation current from output full-bridg...

Based on Lyapunov finite-time stability theory and backstepping strategy, we put forward a novel fixed-time bounded H infinity tracking control scheme for single-joint manipulator system with input saturation. The main objective is to maintain that the output variable tracks desired signal at fixed time. advantages of this paper are settling time error converging origin independent initial cond...

This paper presents two stabilizing control methods for discrete time bilinear systems. One is a stabilizing controller for single input systems, and the other is a generalized stabilizing control method for discrete time multi-input bilinear systems. The proposed control methods guarantee the stability for each closed loop systems with single-input case and multi-input case, respectively. This...

a fault-tolerant control (ftc) methodology has been presented for nonlinear processes being imposed by control input constraints. the proposed methodology uses a combination of feedback linearization and model predictive control (flmpc) schemes. the resulting constraints in the transformed process will be dependent on the actual evolving states, making their incorporation in the design context ...

Technical reports from the Automatic Control group in Linkping are available by anonymous ftp at the address ftp.control.isy.liu.se. This report is contained in the compressed postscript le 2018.ps.Z. Abstract We present results concerning the parameter estimates obtained by prediction error methods in the case of input signals that are insuuciently rich when considered locally in time. As is i...

Linear constant-coefficients control systems with output on arbitrary time scales are studied. Kalman criteria of controllability and observability are extended to such systems. The main problem is to find criteria for an abstract input/output map to have a realization as a system on the time scale. Two different characterizations of realizability are proved. They extend the classical results o...
