Combined Control System for Structural and Parametric Uncertain Non-Affine Plants with Delay in Control

Under conditions of priori parametric and structural uncertainties and influence of external noise, the synthesis of combined control law for class of non-affine single-channel plants with scalar output in the presence of control delay is considered. To compensate the negative effect of known delay in control the predictor-compensator is connected in parallel with the plant in the system. The synthesis of structure of the combined regulator is based on use of the hyperstability criterion. Estimates of unmeasured state variables are obtained with the help of filter corrector; therefore, the synthesized system is L-dissipative. To confirm the operability of the obtained system and ensure the required quality of its transient processes, it is performed simulation modeling of the synthesized system. The results of simulation showed that the developed system satisfies the required properties and provides the desired quality of the non-affine plant functioning in the presence of control delay and uncontrolled external disturbances.
