1. A non-transitory, computer-readable medium comprising instructions, wherein the instructions, when executed by a processor, are configured to cause the processor to:
control a target speed range of a compressor of a heating, ventilation, and air conditioning (HVAC) system based on a comparison of an operation coordinate of the compressor with a target region of an operational envelope of the compressor, wherein the operational envelope defines compressor operation coordinates corresponding to a range of evaporating temperatures and a range of condensing temperatures of a working fluid, and the operation coordinate is defined by data indicative of a first temperature of the working fluid exiting the compressor and a second temperature of the working fluid entering the compressor;
iteratively adjust an upper threshold speed of the target speed range or a lower threshold speed of the target speed range while the operation coordinate is within a control region of the operational envelope, wherein the control region is outside of the target region, and
maintain the target speed range based on a determination that the operation coordinate transitions from the target region or the control region of the operational envelope to a deadband region of the operational envelope, wherein the deadband region is between the target region and the control region.
