The innovative STC® technology allows to design directly from the experimental date the parameters for automatic controls software applied to complex and non linear systems.

Several application of internal model control, robust controls, model predictive controls accounting for non linearities and constraints have been realized in numerous projects in the automotive, aerospace and energy fields, such as described in the following.


ico-automotiveControl of semi-active suspensions


Purpose: Development of algorithms for a control of semi-active suspensions, in order to improve passenger comfort and vehicle handling. Using STC® technology has been developed a procedure for deriving, from experimental data, highly affordable control of semi-active suspensions.

Value: The use of STC® technology in design and calibration of control permit an important time reduction of development. Control performances are increased by 10-25%.


Control of multi air actuator

Development of an alternative control system for the Multi Air actuator valve in internal combustion engines. Modelway, using STC® technology, has developed, implemented and tested the control of the actuator in order to improving performances, design and calibration times. This solution allows to design controls directly from experimental data, assessing accuracy and conduct robustness analysis for optimization purpose.

Value: Performances of control increased  approx. by 20%  and the calibration time has been reduced from 2 months to 2 weeks.


ico-aerospaceFault tolerant control of Unmanned Aerial Vehicles (UAV)


Purpose: Development of a UAV fault recovery procedure, based on the STC® technique. It has been implemented and tested on an UAV designed by the customer. UAV has often multiple surfaces for flight control and actuators; the fault recovery state-of-art procedures are based on Linear Quadratic Regulator design, which does not explicitly accounts for limited actuator actions. Such limits may become relevant in case of fault on some of control surfaces.

Value: For most of critical faults, significant improvements have been obtained in control performances such as lateral wind attenuation, turn and pitch manoeuvres.


ico-automotiveAir boost pressure control for turbocharged internal combustion engines

Purpose: Development of a non linear MIMO air boost pressure control system for Turbocharged Internal Combustion Engines. The data used for STC® design are measured from the tests used for evaluating engine dynamics.

Value: Systematic design of an integrated feedback MIMO control for EGR and VGT actuators.This solutions allows a combination of improved control performances and reduced development effort in design, implementation and calibration time.


ico-automotiveADAS for Combined Lane Keeping and Driver’s Steering
Purpose: Design of a feedback lane keeping control system allowing the driver to have the complete control of the vehicle lateral dynamics when acting on the steering wheel. The lane keeping control required EPS, vision system and steering torque sensor.

Values: The lane keeping control is always operating, i.e. no switching strategy is used, also the driver can steer as if the automatic control would not be acting. If the driver, for any reason, is not acting on the steering wheel, the control system smoothly tracks the car to the lane center.


ico-automotiveControl of Linear Electric Actuator
Purpose: Development of a control to provide position control of linear electric actuators for brake by wire application. The STC® technology performs an automatic procedure to compute the control parameters from experimental data.The control robustness and the rejection of band disturbances have to be guaranteed for the series production

Values: The control allowed significant improvements in terms of time reduction in control designing and calibration compared with the existent control system. The control robustness has been guaranteed for the series production.
