Output Feedback Tracking Sliding Mode Control with Parallel Feedforward Compensator
A new design method of output feedback type tracking sliding mode control (SMC) is proposed in this paper. Stability of the control system and the tracking performance to the reference input are achieved by using the parallel feedforward compensator (PFC), which guarantees almost strict positive realness (ASPR) of the plant, and the so-called internal model. Effectiveness of the method is shown...
متن کاملOn LQ-control of magnetic bearing
Abstract--Control theory gives very few examples of control systems for which the closed-form solution to the LinearQuadratic (LQ) optimization problem exists. This paper describes two such systems of 2nd and 4th order concerning magnetic bearings and gives the closed-form solutions to the LQ-problems. The controller obtained provides the LQoptimal bearing forces and minimizes copper losses in ...
متن کاملAnalysis of Vibration Characteristics of PD Control Active Magnetic Bearing and Cracked Rotor System (RESEARCH NOTE)
Crack fault of rotor is one of the most prominent problems faced by magnetic bearing rotor system. In order to improve the safety performance of this kind of machinery, it is necessary to research the vibration characteristics of magnetic bearing cracked rotor system. In this paper, the stiffness model of the crack shaft element was established by the strain energy release rate (SERR) theory. T...
متن کاملA Youla-Kucera parametrized adaptive feedforward compensator for active vibration control with mechanical coupling
Most of the adaptive feedforward vibration (or noise) compensation systems feature an internal ”positive feedback” coupling between the compensator system and the correlated disturbance measurement which serves as reference. This may lead to the instability of the system. Instead of the standard IIR structure for the adaptive feedforward compensator, the paper proposes a Youla-Kucera parametriz...
متن کاملAdaptive Pid Control for Nonlinear Systems with a Parallel Feedforward Compensator
In this paper, we propose a design method of an adaptive PID controller based on output feedback for nonlinear systems with a higher order relative degree and disturbances. To realize an adaptive PID control system, we introduce a PFC for a nonlinear system which does not satisfy OFEP(Output Feedback Exponentially Passive) conditions and design an adaptive feedforward input with a structure of ...
