This study proposes the application of non-parametric filters based on the Singular Spectrum Analysis (SSA) method in linear and nonlinear control problems. The SSA is a general method for time series analysis that decomposes a signal into a set of additive components, including the measurement noise, in an adaptive way. It is highly adaptive to the behavior of signals and does not require any statistical assumptions. These flexible characteristics motivate the usage of SSA for control applications that demand filters with changing order or parameters, according to unknown disturbances of modeling errors, and applications that require the generation of smooth trajectories and commands. To show the feasibility of linear control, the SSA was used to attenuate the measurement noise in PID control loops, and in the nonlinear case, the SSA was used in an online trajectory generation approach. Experimental results showed that the SSA reduces the system's sensitivity to noise, allowing the use of the derivative action while maintaining satisfactory performance. As a trajectory filter, the SSA successfully generated bounded derivatives from discontinuous input signals with similar response curves as those obtained by a parametric trajectory filter.

Numerous electrical machines use power converters for their efficient operation. However, their insulations experience a fast deterioration due to high frequency electrical stresses. This loss of insulation can lead into ground faults, which are the most common electrical faults. Convectional protection relays are not specifically designed to protect electrical drives. Moreover, relays' malfunction could be provoked because of commutation noises, or DC and AC fault current's components influence in their measurement. Therefore, if the fault is not detected in time, it can be developed into a more severe fault. This paper proposes a detection method for high resistance double line-to-ground faults in electrical drives based on a grounding resistor placed in the midpoint of the DC side. The method has been developed for DC/AC systems and it is based on the voltage measurement in the grounding resistor and in the AC phases. Afterwards, performing a frequency domain analysis of the grounding resistor voltage and comparing its fundamental harmonic phase differences with the AC voltage phasors, the double line-to-ground fault incipient zone (DC and/or AC) can be detected, and also, the DC faulty pole or AC faulty phase can be discerned. The method has been verified through computer numerous simulations and experimental tests in a 140 kW power converter, obtaining satisfactory results in the fault detection. However, the exact location of each ground fault still being incognita.
