Time-based pulldown and pullup using trajectory tracking and box parameter learning

A system for controlling pulldown or pull-up of a temperature of a conditioned space, comprising:

• a transport climate control system configured to control a temperature of the conditioned space of a transport unit;
• and
• a controller configured to:
• receive a time parameter for a pulldown or pull-up operation for the conditioned space, wherein the time parameter is one of a period of time over which the pulldown or pull-up operation is to be completed or a specific time by which the pulldown or pull-up operation is to be completed;
• determine a pulldown or pull-up trajectory based on a model of a response of the conditioned space to operation of the transport climate control system and the time parameter, wherein determining the pulldown or pull-up trajectory is based on an energy efficiency over the course of completing the pulldown or pull-up operation according to the time parameter, and
• direct operation of the transport climate control system based on the determined pulldown or pull-up trajectory so as to perform the pulldown or pull-up operation.
