This paper analyzes features and problems related to the application of the simplex sliding mode control to systems with mono- directional actuators and integrators in the input channel. The plain use of the method formulated in previous contributions results in unacceptable behaviors, such as control laws (the output of the mono-directional actuators), which increase without bounds. It is proposed a non trivial modification of the original algorithm; the new simplex strategy allows the perfect fulfillment of the control objectives by means of bounded inputs from the actuators.
