Various notions of controllability for general (i.e. possibly non-regular) implicit linear systems are considered. Some genericity properties of the corresponding controllable systems are established.
Keywords: Implicit linear systems; controllability; matrix pencils; perturbations of control-lable systems; generic properties; Hautus condsitions.
