Electrochromic glass hysteresis compensation for improved control accuracy

A method for controlling operations of an EC device, comprising:

• developing a hysteresis model, by a control module coupled to an EC device, which represents a hysteresis effect of a leakage current of the EC device;
• tracking, by the control module, one or more prior operating histories of the EC device;
• and
• transitioning the EC device, by the control module, to a target transmission level with compensation for the hysteresis effect of the leakage current based in part on a current transmission level, the one or more prior operating histories, and the hysteresis model of the EC device.

A non-transitory computer readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to:

• develop a hysteresis model representing a hysteresis effect of a leakage current of an EC device;
• track one or more prior operating histories of the EC device;
• and
• transition the EC device to a target transmission level with compensation for the hysteresis effect of the leakage current based in part on a current transmission level, the one or more prior operating histories, and the hysteresis model of the EC device.
