Control Strategies andKinematic Coupling

Modern sunshades often incorporate sensors for solar angle, ambient light, temperature, and wind speed. The control system uses these inputs to determine the desired shade position, which is then mapped to the actuator command using the inverse kinematics of the mechanism. For example, a rotating louver might require a non-linear mapping between the actuator stroke and the louver angle due to the geometry of the linkage. By calculating this mapping ahead of time or using real-time kinematic solvers, the control system can achieve precise positioning even under varying windŁadunki.
