Designing the Algorithms

Practical Applications of System Theory Speeds Development

Control Systems

Advanced algorithms efficiently provide practical solutions to complex problems.

Initial design of an algorithm is performed in a relatively short time frame.

Optimizing parameters of an algorithm enables adaption or fine-tuning of the algorithm for the specific application.

Communications and RF Sensors

Collaboration with your staff yields algorithm designs that meet all performance requirements.

Our goal is to provide your staff with practical algorithms and the knowledge to fine tune them.


 
Our algorithm design experience applies system theory to practical algorithms for control systems, communications, and RF sensors.
Algorithms Examples
Digital
Control
  • Simplified first, second, and third order digital controllers used in multiple-unit parallel solid-state power conversion system to one standardized first order form with no degradation in performance
     
  • Proved that the state of the power sharing among units of the multiple-unit parallel solid-state power conversion system can enter the uncontrollable subspace when a unit goes off line and proved that algorithm reinitialization solves the problem
     
  • Designed digital control algorithms for tracking single targets in angle
