digital control, delta operator, fixed-point arithmetic, PID control, simple adaptive control

The methodology we propose for realizing energy- and space-saving adaptive control algorithms is based on pulse width modulation (PWM) with a modified delta operator. The dynamic calculation range is at least twice that of the conventional range, making it very useful in embedded real-time intelligent and micromechatronic systems because complex control algorithms can be implemented in fixed-point arithmetic with short words. Simulation results for PID control and simple adaptive control demonstrate the practicality and effectiveness of our proposal.
