Various mechanical systems demand precise positioning control strategies. Cascade control of DC motor driving unit is still one of the most popular structures of automatic positioning. One of the main problems of this structures are the oscillations of the current, speed and position. All of these oscillations negatively effect on the electronics and mechanics live time. The method of input shaping (or in general signal shaping) is used to reduce this problem. The signal shaping was implemented for reference torque, reference speed and reference position signal. The common work of multiple input shapers is also presented. The results were compared with control without of signal shaping. The robustness for parameters change was tested. The research was conducted in MATLAB/Simulink environment.
