**Title:**CLASSICAL AND HIGHER SYMMETRIES OF CONTROL SYSTEMS

**Authors:**V. N. CHETVERIKOV, A. N. KANATNIKOV, A. P. KRISHCHENKOClassical and higher infinitesimal symmetries of control systems are studied. Defining equations for classical external symmetries are obtained in the general and affine cases. For computing higher symmetries we suggest a simple procedure involving algebraic operations and differentiation but not integration. Relations between classical symmetries and first integrals of control systems are established. An example is considered to illustrate our methods.
