In this work, we consider two different techniques based on reservoir engineering process and quantum Zeno control method to analyze the decoherence control mechanism of a charged magneto-oscillator in contact with different type of environment. Our analysis reveals that both the control mechanisms are very much sensitive on the details of different environmental spectrum ( J  ( ω )), and also on different system and reservoir parameters, e.g., external magnetic field ( r c ), confinement length ( r 0 ), temperature ( T ), cut-off frequency of reservoir spectrum ( ω cut ), and measurement interval ( τ ). We also demonstrate the manipulation scheme of the continuous passage from decay suppression to decay acceleration by tuning the above mentioned system or reservoir parameters, e.g., r c , r 0 , T and τ .
