AN ALGORITHM FOR COMPACT FIXED-POINT IMPLEMENTATION OF DIGITAL CONTROLLERS


We propose and study the algorithm of digital controllers implementation in fixed-point arithmetic based on the adaptive selection of a discrete transform and a discrete operator (z- or δ-operator). An experimental verification of the proposed criteria for the transform and operator selection is performed, also results of the proposed algorithm testing are given. Suggested approach made it possible to reduce the number of utilized logic elements in the FPGA or ASIC implementation of controllers up to 2-3 times and more in comparison with the traditional technique based on the application of the Tustin transform and z-operator, and also reduce the development complexity. The obtained results are of practical importance in the electronic units design for autonomous embedded systems, space vehicles and other objects with restricted mass, dimensions and power consumption, giving the possibility to overcome these restrictions
