Finding the PID Controller Parameters in Synchronization Between Hyperchaotic Oscillators in QAM (Quadrature Amplitude Modulation) Communication System Using Particle Swarm Optimization

Oscillators, which form the basis of chaotic communication, can be designed using different mathematical models. Hyperchaotic oscillators, unlike classical chaotic oscillators such as Chua and Sprott, have been developed to generate more chaotic signals. To ensure synchronization of such oscillators, the controller coefficients were determined using particle swarm optimization. This study attempted to achieve synchronization between hyperchaotic oscillator systems using various optimization algorithms, and the results demonstrated that the PID controller was inadequate for these systems.
