Abstract
A suspension work platform hoist system having a variable acceleration motor control system and a tilt control system. The tilt control system includes at least one tilt sensor to sense a tilt angle of the work platform and generate a tilt signal. A tilt controller receives the tilt signal and generates a speed control signal, which is used by the variable acceleration motor control system to control the operation of the hoist motors to maintain a tilt angle setpoint as the work platform is raised and lowered. The tilt control system may include a settling mode having a settling tilt angle setpoint, wherein the settling mode prevents the work platform from being raised or lowered until the tilt angle of the work platform reaches the settling tilt angle setpoint.
