We propose a new method to derive invariants for LTI systems with uncertain inputs, i.e. systems of the form $\dot x(t) = Ax(t) + Bu(t)$ with state vector x(t)∈ℝn and uncertain input u(t)∈ℝm bounded by u(t)∈U⊆ℝm for all t≥0. Our approach is based on the real canonical form and the resulting invariants are conjunctions of bounds on linear and quadratic forms in the state variables x(t).
