Model Reference Control in Second- Order Dynamic Systems

چکیده
In this paper, existence and solution of the feedforward plus feedback control law for model reference control of a class of second-order dynamic systems are investigated. A necessary and sufficient condition for the existence of the controllers is established. Based on a result of parametric eigenstructure assignment in second-order dynamic systems, general complete parametric expressions for the controllers are presented and a parametric approach to design the feedforward plus feedback control logic is proposed. The parametric approach offers all the design degrees of freedom which can be further specified to satisfy some additional system performances. In addition, the parametric method utilizes directly the original system data, and thus is convenient to use in applications. A numerical example shows the effect of the proposed parametric method.

متن کاملDynamic Sliding Mode Control of Nonlinear Systems Using Neural Networks
Dynamic sliding mode control (DSMC) of nonlinear systems using neural networks is proposed. In DSMC the chattering is removed due to the integrator which is placed before the input control signal of the plant. However, in DSMC the augmented system is one dimension bigger than the actual system i.e. the states number of augmented system is more than the actual system and then to control of such ...
