The pursuit of achieving the maximum power in microscopic thermal engines hasgained increasing attention in recent studies of stochastic thermodynamics. Weemploy the optimal control theory to study the performance of Brownian heatengines and determine the optimal heat-engine cycles in generic dampedsituation, which were previously known only in the overdamped and theunderdamped limits. These optimal cycles include two isothermal processes, twoadiabatic processes, and an extra isochoric relaxation process at the upperstiffness constraint. Our results not only interpolate the optimal cyclesbetween the overdamped and the underdamped limits, but also determine theappropriate friction coefficient of the Brownian heat engine to achieve themaximum power. These findings offer valuable insights for the development ofhigh-performance Brownian heat engines in experimental setups.
