Is a higher degree loop possible while maintaining stability? Commanding
frequency while measuring phase is one pole, integrating the result of the
phase comparison is a second pole and closing the loop will result in
oscillation unless a zero is inserted (the P in PID).

How would stability be maintained?

Thanks
