Control Study of Precision Giant Magnetostrictive Actuator Based on Active Disturbance Rejection Control Technology
Introduce the structure and working principle of precision giant magnetostrictive actuator and establish the actuator system object transfer function model so as to design a suitable active disturbance rejection controller (ADRC). According to the model analysis, regard the actuator system as a first-order inertia object with dead time to construct second-order ADRC, use MATLAB for parameter tu...
متن کاملRobust Adaptive Actuator Failure Compensation of MIMO Systems with Unknown State Delays
In this paper, a robust adaptive actuator failure compensation control scheme is proposed for a class of multi input multi output linear systems with unknown time-varying state delay and in the presence of unknown actuator failures and external disturbance. The adaptive controller structure is designed based on the SPR-Lyapunov approach to achieve the control objective under the specific assump...
متن کاملAnalysis and Design of Switched Linear Systems in the Presence of Actuator Saturation and L2 Disturbances
This paper considers the problem of disturbance tolerance/rejection for a family of linear systems subject to actuator saturation and L2 disturbances. For a given set of linear feedback gains, a given switching scheme and a given bound on the energy of the disturbances, conditions are established in terms of linear or bilinear matrix inequalities under which the resulting switched system is bou...
متن کاملPersistent Bounded Disturbance Rejection for Linear Systems subject to Actuator Saturation
This paper studies the problem of persistent bounded disturbance rejection for linear continuous-time systems subject to actuator saturation. By using the Lyapunov function method, a sufficient condition is given in terms of linear matrix inequalities, which ensures the internal stability and the desired L1 performance of the closed-loop systems. An optimization procedure is proposed to obtain ...
متن کاملPeriodic Disturbance Rejection Using Two Dof Repetitive Control for a Motor Gear Transmission System
In this paper, we design and analyse a two degree-of-freedom (TDOF) repetitive control system for a motor/gear transmission system with actuator saturation. Modifications are made for our previous design to incorporate the performance-limiting element, i.e. actuator saturation, to acquire lower order controller, and to achieve faster computation. Furthermore, structured singular value (μ) is us...
