A ring of unidirectionally coupled phase oscillators is simple and easy to implement but not suitable for application central pattern generators (CPGs) owing the presence coexisting stable equilibria corresponding a gait useless pattern. In this study, we propose novel approach applying CPGs by incorporating additional circuitry that alters state transition timing. This comprises linear-feedback shift register comparator. Our proposed model successfully generated typical hexapod patterns, such as wave tripod well patterns between them. The projected Poincarè map was numerically derived reveal possesses unique equilibrium these desired patterns. Furthermore, implemented on field-programmable gate array (FPGA) experimentally validate its effectiveness in generating gaits robot. Finally, demonstrated require fewer FPGA resources compared with conventional state-of-the-art CPG models.

<p>Half-center oscillators are typical small circuits that crucial for understanding CPG. The complex rhythms of CPG closely related to certain diseases, such as epilepsy. This paper considered the influence electromagnetic induction on discharge mode half-center oscillators. First, we analyzed response individual firing neuron when slow-variable parameters vary. We also discussed changes in dynamic bifurcation structure intensity varies. Furthermore, determined effects mutually inhibitory and self-inhibitory synaptic rhythm different responses induced by interventions, showed synapses modulate weakly self-inhibition have a significant impact rhythm. Finally, with change parameter values, combined autapse were symmetric asymmetric modes. It was found synchronous state had more robust than asynchronous state.</p>
