In this paper, the differential equations of motion of nonholonomic systems with servoconstraints were constructed. Based on the theory of symmetries and conserved quantities of nonholonomic systems with servoconstraints, the perturbation to the symmetries and adiabatic invariant of nonholonomic systems with servoconstraints were discussed. First, the concept of high-order adiabatic invariant of nonholonomic systems with servoconstraints was proposed. Then, the conditions for existence of the exact invariant and adiabatic invariant were proved, and their forms were given. Finally, an example is presented to illustrate these results.
