Terminal control of processes in chemical reactors using orbital linearization
Engineering Education # 10, October 2013 DOI: 10.7463/1013.0612563 The authors consider an affine third order system which describes action of a chemical batch reactor with a ternary working mixture. The terminal control problem for this system with restrictions on state variables was investigated. Solution to this problem is based on the orbital linearization approach by which the original problem is transformed to a terminal problem for a non-stationary second-order system in a canonical form. For the transformed terminal problem conditions for solution existence were obtained; a method of obtaining this solution was also proposed. Operability of the proposed method was illustrated by mathematical simulation.
Affine system transformations to the canonical form using change of the independent variable
Engineering Education # 07, July 2013 DOI: 10.7463/0713.0566578 УДК: 517.938 Change of the independent variable (time-scaling) gives an additional degree of freedom for equivalence conversions of dynamical systems. Affine system transformation to the canonical form is a standard technique in the design of nonlinear control systems. In this paper transformations of a stationary affine system to the canonical form, using time-scaling, were investigated. Integratable and non-integratable changes of the independent variable were considered. It was shown, that the affine system can't be transformed to the canonical form using integratable time-scaling. Conditions of the possibility of transformation to the regular canonical form using non-integratable time scaling were obtained for single-input affine systems of the third order.
Features of transition to path coordinates in a problem of path stabilisation
Engineering Education # 07, July 2012 DOI: 10.7463/0712.0445496 The model of the wheeled robot with automobile configuration of wheels in a problem of path stabilisation is considered. Conditions at which transition from the Cartesian coordinates to the trajectory coordinates at the path stabilization problem is correct are investigated. Performance of these conditions for the elementary types of a trajectory of the robot is analyzed.
