The design follows the requirement of the fastest possible transient processes without overshoot. It is limited to the case when the control signal can potentially attack both the upper and lower saturation limit. For the basic PD controller tuning it is usually enough to use approximation of the original plant by the I2Td model (double integrator + deadtime). The piecewise constant (or slowly varying) disturbances are compensated by a windupless integral action added to the controller output. Here, the loop properties can be improved by using also more sophisticated 2nd order plant approximation.

A triple integrator plant has been used to illustrate the design. The paper is focused on the synthesis in a computer algebra system MAPLE, which is shown "step by step" in the paper. The designed control can be applied to a broader class of systems.

The design combines the well known time optimal control with the linear pole assignment control, i.e. the control consist of n phases similar to the time optimal control, however the transients between these phases are "smooth" and the dynamics of the transients is given by the closed loop poles.

By examining properties of the control loop with the reduced relative degree of the original plant, it prepares methodology for applying the achieved results for controlling higher order systems with constained input. The success of the relative degree reduction by introduction of a fictive output that involves derivatives of the original output is shown to be dependent on the anticipation of the working range of the controlled system.

It is starting with analysis of the institutional context of education in the control area and continuing with some examples of the author's experience in building up control experiments.
