Abstract：
In this paper; the author considers a general control problem about the systemof thermoelasticity of type I. By introducing some unique continuation property of thecorresponding adjoint system and a suitable observability inequality for an elastic equation; using compact decoupling technique and variational approach; the exact-approximatecontrollability of the abstract thermoelasticity of type I is obtained. Finally; the authorapplies her abstract result to the exact-approximate controllability of the linear system ofthermoelasticity
