The effect of ion-neutral collisions is also considered here. Using the reductive perturbation technique, a forced modified Korteweg-de Vries (FMK-dV) equation is obtained in the presence of an externally applied force. The periodic, quasi-periodic, and chaotic motions of IA waves are investigated by considering three-dimensional phase portraits and time-series analysis. It is noted that ion-neutral collisional frequency, strength, and frequency of the external periodic force play an important role in controlling the dynamic motion of ion-acoustic waves. Moreover, it is found that the strength of the external perturbation can be considered as the main parameter for the transition from quasi-periodic motion to chaotic motion.}, number={4}, journal={Journal of Theoretical and Applied Physics}, publisher={OICC Press}, author={Mehdipoor, Mostafa and Mohammadmoradi, Yaghoob}, year={2023}, month={Nov.}, keywords={Traveling waves, Chaotic motions, Collisional plasmas, Forced modified K-dV equation, Ion-acoustic waves} }
