Can someone help me check if this active filter is a voltage-controlled power supply type or a multiple feedback type? Also, if I want to change it to a low-pass filter with a cutoff frequency of 1kHz, how should I determine the parameters of the capacitors and resistors in the circuit?

Voltage-controlled voltage source type. I have replied to you in the post about low-pass filters.
