Block diagram illustrating a control system for generating spikes based on error signals.

The system calculates the error $e\_n$ by subtracting the measured response from the desired response:

The error $e\_n$ is fed into three parallel processing blocks:

• Proportional term: $g\_P\; \backslash cdot\; e\_n$
• Integral term: $g\_I\; \backslash cdot\; \backslash sum\_\{i=0\}^\{n\}\; e\_i$
• Differential term: $g\_D\; \backslash cdot\; (e\_n\; -\; e\_\{n-1\})$

The outputs of these blocks are summed to produce the stimulation rate:

The stimulation rate is then input to the spikes generator, which outputs the final signal.
