A nonlinear controller for AHU systems based on prescribed time control

This paper develops an adaptive practical prescribed-time controller for simultaneous humidity and temperature regulation of an air handling unit (AHU) subject to bounded non-vanishing disturbances. Under the admissible cooling/dehumidification operating conditions, the Lyapunov analysis shows that the output-tracking errors enter an explicitly bounded residual set no later than $$T=T*-ε
